Typical Applications
SN74LVTH16374-EP is suitable for 6 applications: Avionics Pipeline Data Registers, Medical Imaging Bus Isolation, Industrial Address and Data Latching, Synchronous Pipeline Storage in Test Equipment, Communications Backplane Data Buffering, Data Acquisition Digital Control.
Avionics Pipeline Data Registers
In space-constrained avionics and defense electronics, the SN74LVTH16374-EP provides sixteen positive-edge-triggered registers with a common clock, enabling wide synchronous data pipelines in a single 48-pin package. Its EP qualification supports defense and aerospace program documentation requirements that commercial parts cannot satisfy. The ABT BiCMOS technology delivers fast edge rates with TTL drive capability, while the 3-state outputs allow the registered data bus to be shared with other bus masters, reducing board-level device count and routing complexity.
Recommended
Medical Imaging Bus Isolation
Medical imaging equipment such as ultrasound and digital radiography systems requires clean isolation of shared data buses between acquisition and processing stages. The SN74LVTH16374-EP's 3-state outputs place all sixteen Q outputs into high impedance when OE is high, fully isolating bus segments, while its EP qualification aligns with medical application support defined by TI. Operating from a 3.3-V rail with 5-V TTL input compatibility allows direct interface to legacy sensor front ends running at 5 V without additional level-shifting circuitry.
Recommended
Industrial Address and Data Latching
In industrial control and PLC backplanes, the SN74LVTH16374-EP latches address or data words on a common rising clock edge, providing deterministic timing versus level-sensitive latches. The LVTH family TTL drive handles noisy factory-floor bus environments, and the 3.3-V supply with 5-V TTL input tolerance simplifies mixed-voltage retrofits of legacy 5-V controllers. A single device replaces two octal flip-flops, cutting board area and BOM count while the common OE enables clean bus handoff between microprocessor and peripheral sections.
Recommended
Synchronous Pipeline Storage in Test Equipment
Test and measurement instrumentation uses registered 16-bit stages to pipeline ADC results and control words across clock domains. The SN74LVTH16374-EP's positive edge-triggered architecture with common CP ensures all sixteen bits update simultaneously, eliminating skew between octal halves. ABT technology provides balanced drive and fast propagation suited to moderate-speed clocking, while 3-state outputs allow the same registered bus to be read by multiple measurement subsystems, one at a time, through OE control.
Recommended
Communications Backplane Data Buffering
Telecom and networking line cards register data between the backplane interface and the processing FPGA or CPU. The SN74LVTH16374-EP buffers 16 bits per device with the drive strength of ABT technology, sustaining signal integrity across backplane traces. TTL input compatibility with 5-V environments supports legacy backplane signaling while running the card core logic at 3.3 V. Its EP qualification also covers defense communications variants, giving one qualified BOM line across commercial and defense program builds.
Recommended
Data Acquisition Digital Control
In data acquisition systems, the SN74LVTH16374-EP registers channel-select, sample-control, and status words between the host controller and the analog front end. Simultaneous 16-bit clocking guarantees glitch-free control-word transitions, which matters when toggling multiplexer addresses feeding precision converters. The 3-state outputs allow a shared control bus across multiple acquisition cards, selected through OE, while the low dynamic power of BiCMOS LVTH keeps the card power budget predictable in multi-card chassis designs.

Key Differentiators
- EP qualification for defense, aerospace, and medical (vs SN74LVTH16374DGGR)
- 16-bit integration replaces two octal flip-flops (vs CD74HC374)
- 5-V TTL input compatibility at 3.3-V supply (vs SN74ABT162841)
Design Notes
Bypass VCC with a 0.1-uF ceramic capacitor placed within a few millimeters of pin 48, plus bulk capacitance on the board. With sixteen LVTH outputs switching simultaneously, simultaneous-switching current can create supply droop and ground bounce; use a solid ground plane and multiple ground vias to the 48-pin package's ground pin.
ABT technology produces fast edge rates; series-terminate long bus traces (22-33 ohm) to control ringing and reduce EMI. Keep clock (CP) traces short and away from data lines to minimize skew and crosstalk. Ensure OE deassertion timing avoids bus contention when two devices share a bus.
Tie all unused D inputs to VCC or GND - floating BiCMOS inputs can oscillate and increase current draw. Do not leave OE floating. Note that this device provides two clock inputs (1CP for flip-flops 1-8, 2CP for 9-16); connecting both clocks together is standard practice for 16-bit synchronous operation but must be explicit in the design.
