Flip Flops datasheet and documents for SNJ54HC74FK

SNJ54HC74FK

Flip Flops Overview

The SNJ54HC74FK is a military-grade dual positive-edge-triggered D-type flip-flop from the Texas Instruments SNJ54HC series. It features non-inverting outputs and includes dedicated preset (PRE) and clear (CLR) inputs for direct control of the output state independent of the clock signal. The device utilizes CMOS technology, operates within a supply voltage range of 2V to 6V, and supports a maximum clock frequency of 28MHz. It is housed in a 20-lead ceramic flatpack (FK package) designed for high-reliability applications requiring extended temperature stability.

Flip Flops Feature Summary

Dual positive-edge-triggered D-type flip-flops with complementary outputs
Independent active-low preset and clear inputs for direct state control
Military-grade reliability with extended operating temperature range
CMOS construction ensuring low power consumption and high noise immunity

Flip Flops Applications

Military aerospace data acquisition systems
High-reliability industrial control logic
Spacecraft telemetry and command registers
Harsh environment digital signal processing interfaces

Flip Flops Procurement Notes

Verify the specific suffix 'FK' corresponds to the ceramic flatpack package variant when sourcing. Confirm that the component meets all required military specifications and environmental testing standards for your application. Ensure compatibility with existing board layouts due to the specific footprint dimensions of the FK package type.

Flip Flops Selection Notes

Select this component when military-grade radiation tolerance and wide temperature operation are mandatory. Compare propagation delay characteristics against standard commercial variants if speed is critical. Ensure the design accounts for the specific pinout configuration of the ceramic flatpack package during PCB layout.

Flip Flops Part Context

This part belongs to the SNJ54HC family, which denotes military-grade HC (High-speed CMOS) logic devices. Unlike commercial SN74HC counterparts, these components undergo rigorous screening and testing to ensure performance under extreme conditions. The family provides standardized logic functions with enhanced durability for defense and aerospace sectors.
