EP910DM883B Overview
What is an EPLD? An EPLD (Erasable Programmable Logic Device) is a non-volatile programmable logic device that combines the architectural flexibility of a PLD with erasable (UV-erasable) configuration memory. It sits in the taxonomy: programmable logic -> PLD -> EPLD -> CMOS EPLD. EPLDs were widely used before modern FPGAs and CPLDs became dominant, and remain in service today in legacy industrial, military, and aerospace systems where long-life-cycle, pin-compatible replacements are mandatory.
Key features include a typical propagation delay of 40 ns (tPD), a maximum clock frequency of 25 MHz, 24 dedicated macrocells connected via a global interconnect bus, and support for both combinational and registered logic. The PAL-type AND-OR-NOT architecture delivers predictable, deterministic timing. The device operates from a single 5 V supply and is rated across the military temperature range of -55 °C to +125 °C thanks to the /883B MIL-STD screening.
The EP910DM883B is housed in a hermetic ceramic DIP-40 (CDIP-40) package that provides exceptional reliability in shock, vibration, and thermal cycling environments. The /883B suffix denotes full MIL-STD-883B Class B processing, including burn-in, temperature cycling, and Hermeticity testing.
Typical applications include military and aerospace avionics, industrial control logic glue, legacy interface bridging, and pin-compatible replacement of original Altera Classic EPLDs. The wide temperature range and hermetic package make it ideal for downhole, automotive under-hood, and defense electronics.
When designing with this part, engineers should provide a 5 V ±5% supply and route the 40 DIP pins to a 0.1 µF bypass network near the supply pin. UV-erase window programming requires a 12.5 V VPP pulse; for in-system reprogramming, consider a flash-based CPLD as a modern alternative.

Typical Applications
EP910DM883B is suitable for 7 applications: Military Avionics Logic Replacement, Industrial Control Logic Glue, Legacy Aerospace Interface Bridging, Defense Downhole and Harsh-Environment Logic, Legacy Telecom Backplane Glue, Pin-Compatible Repair Board for Obsolete EPLDs, Educational and Engineering Lab Reference Design.
Military Avionics Logic Replacement
The EP910DM883B fits military avionics logic replacement because its MIL-STD-883B Class B screening (-55 °C to +125 °C) and CDIP-40 hermetic package survive the high-shock, high-vibration, and wide thermal environments of cockpit and flight-control electronics. Designers replace obsolete or counterfeit Altera Classic EPLDs in legacy avionics LRUs without any PCB change because the 40-pin DIP footprint, 24 macrocells, and 5 V supply match the original. The 40 ns tPD is deterministic across temperature, supporting synchronous state machines for radar and navigation interfaces. Compared to newer flash CPLDs, the EPLD is preferred here because the mil-spec screening and pin compatibility reduce re-qualification cost dramatically.
Recommended
Industrial Control Logic Glue
The EP910DM883B works as industrial glue logic because the 24 macrocells, 240 product terms, and PAL-type AND-OR-NOT architecture implement glue-logic functions such as address decoding, bus arbitration, and timing-state machines in PLC, SCADA, and motor-control systems. The 5 V supply, 25 MHz clock frequency, and 36-input/24-output pin budget cover most 8-bit and 16-bit microprocessor interfaces used in legacy factory automation. The CDIP-40 through-hole package handles the through-hole PCB assembly preferred in industrial control cabinets. Compared to a discrete 74LS logic implementation, the EPLD reduces board area by 3-5x and consolidates ECO changes into a single UV-reprogrammable device.
Recommended
Legacy Aerospace Interface Bridging
The EP910DM883B bridges legacy aerospace interfaces such as ARINC 429, MIL-STD-1553, and discrete avionics buses because the 40-pin DIP footprint allows drop-in replacement of end-of-life Altera Classic parts in flight computers and signal conditioners that were qualified in the 1990s. The MIL-STD-883B screening and -55 °C to +125 °C rating are mandatory for line-replaceable units (LRUs) that must operate at altitude and in unpressurized bays. The deterministic 40 ns tPD and 5 V interface match the TTL/CMOS logic levels used in legacy DSP and sensor interfaces. Compared to modern FPGAs, the EPLD is preferred in this slot because the existing LRUs are form-fit-function locked and any re-spin costs hundreds of thousands of dollars in qualification.
Recommended
Defense Downhole and Harsh-Environment Logic
The EP910DM883B fits defense downhole and harsh-environment applications because the MIL-STD-883B Class B burn-in, hermetic CDIP-40 package, and -55 °C to +125 °C temperature range survive the high-pressure, high-temperature, and corrosive atmospheres encountered in oil & gas downhole tools and military ground vehicles. Engineers implement timing-critical sequencing for detonator safing, sensor conditioning, and telemetry encoding in a single reprogrammable device. The 40 ns tPD ensures deterministic sequencing for safing-and-arming logic. Compared to plastic-packaged CPLDs, the hermetic ceramic DIP is the only acceptable form factor for the thermal-cycling and outgassing requirements of these programs.
Recommended
Legacy Telecom Backplane Glue
The EP910DM883B serves legacy telecom backplanes because the 24-macrocell capacity and 36-input interconnect support E1/T1 framing, HDLC channelization, and address-decoding functions on 1980s and 1990s central-office switching equipment that is still in service. The 5 V supply matches the backplane power rail, and the 25 MHz clock frequency is sufficient for 8 Mbps HDLC and 2.048 Mbps E1 framing. The CDIP-40 package survives the convection-cooling environment of telecom cabinets. Compared to modern FPGAs, the EPLD is preferred because legacy telecom operators require form-fit-function drop-in replacements and cannot afford board re-spins.
Recommended
Pin-Compatible Repair Board for Obsolete EPLDs
The EP910DM883B is the ideal pin-compatible repair part for field engineers maintaining obsolete Altera Classic EPLD-based equipment because the CDIP-40 footprint, 24 macrocells, 240 product terms, and 40 ns tPD exactly match the original part. The /883B MIL screening provides the same reliability as the originally-installed component, allowing direct swap without re-qualification of the host system. Stocking EP910DM883B on the maintenance shelf keeps legacy missile, radar, and avionics systems operational. Compared to unauthorized aftermarket or remarkered parts, the /883B screening guarantees authentic MIL-STD-883B Class B compliance and protects program reliability.
Recommended
Educational and Engineering Lab Reference Design
The EP910DM883B is used in university and engineering training labs as a reference Classic EPLD because its 24 macrocells and 240 product terms provide enough logic capacity for teaching PAL/PLA architecture, UV-erase programming, and synchronous state-machine design without overwhelming complexity. The 40-pin DIP package is breadboard-friendly and accommodates 0.1 inch pitch protoboards, eliminating the need for fine-pitch adapters. The 40 ns tPD is slow enough to be observed on a logic analyzer, reinforcing timing concepts. Compared to modern FPGAs, the EP910DM883B is preferred in education because students learn register-transfer-level design without vendor-tool lock-in.

Design Notes
The EP910DM883B requires a regulated 5 V ±5% supply on VCC (pin 40). Estimated: at 25 MHz with all 24 macrocells switching, the device draws approximately 80-120 mA; place a 0.1 µF ceramic decoupling capacitor within 5 mm of VCC and a 10 µF bulk tantalum capacitor on the supply rail. The VPP pin (pin 39) must be held at 0 V during normal operation; only raise VPP to 12.5 V during UV-window programming. Adding a 10 kΩ pull-down on VPP prevents accidental programming during power-up transients.
The CDIP-40 ceramic package provides excellent thermal performance but the hermetic seal limits heat transfer to the leads. Estimated: at 100 mA ICC and 5 V, dissipation is 0.5 W and the junction-to-ambient thermal resistance (theta_JA) is approximately 50 C/W for a still-air socketed installation, giving a 25 C rise above ambient. For high-density multi-EPLD boards, derate to 70% of maximum I/O switching or provide forced-air cooling. In -55 °C cold-soak applications, allow 60 seconds warm-up before clocking at full 25 MHz to prevent timing violations.
Route the EP910DM883B on a double-sided through-hole PCB with a ground plane on the solder side to control switching noise. Keep all 36 input traces shorter than 50 mm to limit reflection and crosstalk on the 5 V CMOS interface. Place the 0.1 µF VCC bypass capacitor on the opposite side of the board directly under pin 40, connected via a 0.5 mm via. For multi-card backplanes, add 33 Ω series-termination resistors on clock inputs to dampen ringing on the global clock distribution.
Do not program the EP910DM883B with a 21 V or 25 V VPP pulse - the absolute maximum VPP is 13 V and over-voltage permanently damages the EPROM cells. Do not exceed the 5.5 V absolute-maximum VCC or the device will suffer latch-up. Always erase the device under a UV eraser for at least 20 minutes at 12.5 V VPP before reprogramming - residual charge in the EPROM cells causes erratic operation. For counterfeit avoidance, source /883B parts only through authorized legacy distributors (Rochester Electronics, Lansdale) and demand MIL-STD-883B Group C/D test reports.
When laying out a CDIP-40 footprint, use a 2.54 mm (0.1 inch) pin pitch with 0.6 mm diameter plated through-holes per IPC-7251. Pad diameter should be 1.7 mm with a 0.15 mm annular ring. Allow at least 1.0 mm clearance between adjacent pads for hand-soldering rework. The UV-erase window is centered on the top of the package - keep the package clear of tall components (heatsinks, inductors) within 5 mm above the window to allow erasure without removing the part from the board.
Compliance Information
MIL-STD-883B Class B screening verified per Altera slash sheet. RoHS, REACH, and lead-free status not stated in verified web data - marked [DATA_NEEDED] in specs[] and unknown here. The CDIP-40 ceramic hermetic package typically contains lead-bearing solder, making RoHS exemption likely but unverified.
