EP610DC-30 Overview
A Classic EPLD is an early-generation programmable logic device that uses EPROM cells to store the configuration. In the broader taxonomy, the EP610DC-30 sits inside the PLD (Programmable Logic Device) family, which is a subset of programmable logic alongside CPLDs and FPGAs. EPLDs were widely adopted in the late 1980s and 1990s as a means of replacing discrete 74-series TTL/MSI glue logic, integrating state machines, address decoders, bus arbiters, and counter/timer functions into a single non-volatile, one-time-programmable (windowed-erasable UV) IC. The Classic device family preceded the MAX series and offers pin-to-pin compatibility across the EP610 and EP910 lines.
Key features include 16 macrocells organized in 4 Logic Expanders, 16 dedicated input pins, and 16 I/O pins with output enable control, plus a programmable clock with global and per-macrocell options. The EP610DC-30 supports a maximum toggle frequency of 100 MHz in pipelined mode, delivers a tPD (pin-to-pin propagation delay) of 30 ns in commercial temperature grade, and offers both registered and combinatorial output modes. The device also features a synchronous preset and asynchronous clear network, plus a security bit to protect proprietary designs after programming.
Architecturally, the EP610DC-30 uses a sum-of-products (AND-OR-XOR) PLA-like structure with a global interconnect that routes the 16 inputs and 16 feedback paths into 4 Logic Expanders, each producing 4 product terms per macrocell. The JEDEC-standard 24-pin ceramic DIP package supports through-hole mounting, which is typical for legacy and aerospace applications where socketed, field-replaceable logic remains preferred.
Typical applications include TTL/MSI glue-logic replacement in industrial controllers, address decoding in 8-bit and 16-bit microprocessor systems (such as 8086 and 68000 bus interfaces), state-machine implementations in telecom and instrumentation, and aerospace/avionics systems requiring ceramic-package reliability. Designers transitioning from 74LS/74ALS logic to a programmable equivalent often select this part for its predictable timing and EPROM non-volatility.
When designing with the EP610DC-30, note that ceramic DIP packages require through-hole PCB footprints and are not compatible with modern surface-mount assembly processes. Programming requires a UV-erasable window (no in-system programmability), and design entry uses legacy tools such as Altera MAX+PLUS II or the older A+PLUS environment. Designers should verify second-source availability (Rochester Electronics and Intel/Altera continue to manufacture this part) before committing to new designs.

Typical Applications
EP610DC-30 is suitable for 6 applications: TTL/MSI Glue Logic Replacement, Microprocessor Address Decoding, State Machine Implementation, Aerospace & Avionics Systems, Industrial Control Systems, Legacy Test & Measurement Instrumentation.
TTL/MSI Glue Logic Replacement
The EP610DC-30 replaces discrete 74LS/74ALS TTL logic by integrating address decoders, bus arbiters, and combinational glue into one non-volatile device. With 16 macrocells and 300 usable gates it can absorb 4-8 SSI/MSI packages, and its 30 ns tPD matches 74LS timing within tolerance. The EPROM non-volatility means logic is available at power-up with no boot sequence, unlike SRAM-based alternatives. The 24-pin CERDIP package drops onto standard through-hole PCB footprints designed for legacy 74LS replacement boards, simplifying field upgrades.
Recommended
Microprocessor Address Decoding
The EP610DC-30 implements address decoding for 8-bit and 16-bit microprocessor systems including 8086, 68000, and Z80 designs. Its 16 dedicated inputs accept full address buses plus control signals (/RD, /WR, /MREQ), and 16 I/O pins produce chip-select outputs for memory and peripheral mapping. The 30 ns propagation delay fits comfortably within the address-to-CS timing window of 8 MHz 8086 and 10 MHz 68000 systems. JEDEC-standard programming files integrate the decoder into one package, replacing 2-3 PAL16L8/20L8 devices.
Recommended
State Machine Implementation
The EP610DC-30 implements Moore and Mealy state machines for instrumentation, telecom, and control applications where deterministic, non-volatile logic is required. Each macrocell supports registered output with synchronous preset and asynchronous clear, and the 4 Logic Expanders provide product-term sharing for large state encodings. With 100 MHz maximum pipelined clock frequency and 30 ns tPD, the device handles telecom bit-rate processing up to 33 MHz comfortably. The EPROM storage means the state machine boots to a known state at power-on.
Recommended
Aerospace & Avionics Systems
The EP610DC-30's ceramic DIP package with UV-erasable window satisfies aerospace and avionics reliability requirements where plastic packages and surface-mount only footprints are unacceptable. The part is used in long-life avionics subsystems including flight-control interfaces, navigation displays, and legacy radar signal processors that require 20+ year field support. Rochester Electronics' continuing-manufacture program guarantees supply for aerospace-grade customers throughout the platform lifecycle. The through-hole CERDIP package also enables socketed field replacement, important in MRO scenarios.
Recommended
Industrial Control Systems
The EP610DC-30 drives discrete I/O expansion, motor-control timing, and PLC ladder-logic equivalent functions in legacy industrial controllers. Its 16 I/O pins interface directly to 5V CMOS/TTL industrial buses, and its EPROM non-volatility ensures controllers come up in a deterministic safe state at power-on - critical for safety-rated industrial machinery. The 30 ns tPD suits PLC scan times of 10-20 ms typical, where the EPLD performs sub-millisecond I/O decoding. Industrial customers value the part's predictable long-term availability via Rochester Electronics.
Recommended
Legacy Test & Measurement Instrumentation
The EP610DC-30 implements timing generators, pulse-width modulators, and counter/timer chains in benchtop and ATE test equipment. Its 100 MHz pipelined clock capability and 16 macrocells produce 4-6 channels of independently programmable timing signals. The CERDIP package allows through-hole PCB assembly consistent with 1980s-1990s instrument designs still in field service. The EPROM non-volatility eliminates configuration memory and simplifies calibration procedures - the instrument powers up ready to measure.

Design Notes
The EP610DC-30 ceramic DIP package requires through-hole PCB mounting - it is NOT compatible with surface-mount assembly processes. Verify your board has DIP-24 footprints before sourcing this part. For new designs requiring SMD assembly, consider the Altera/Intel MAX series (EPM7032S in TQFP-44) which provides in-system programmability and modern footprints.
Place 0.1uF decoupling capacitors as close as possible to the VCC (pin 23) and GND (pin 12) pins of the EP610DC-30. For multi-EPLD designs, use a 10uF bulk tantalum capacitor at the power-entry point. Route the global clock (pin 18) with a 50-ohm controlled-impedance trace if operating above 25 MHz to avoid clock-distortion issues. The UV-erase window requires clearance above the package for erasure access.
The EP610DC-30 is NOT in-system programmable - design changes require a UV eraser (15-30 min exposure at 12 mW/cm^2) and a device programmer supporting the JEDEC-standard EP610 bitstream. Modern design flows use legacy tools (Altera MAX+PLUS II or A+PLUS), not Quartus. Plan for at least one development cycle per design iteration to allow UV erase and reprogram cycles.
Compliance Information
Ceramic DIP package with UV window typically contains lead-bearing solder/glass. Not RoHS compliant due to ceramic-package materials. AEC-Q100 not applicable - this is a programmable logic IC, not an automotive-grade semiconductor in the modern AEC sense. Aerospace and avionics customers use this part under legacy qualification programs.
