54L74W/B

Overview

The SN54L74W/B is a dual positive-edge-triggered D-type flip-flop manufactured by Rochester Electronics. It features independent data inputs, clock inputs, and complementary outputs, along with preset and clear functions. The device utilizes TTL/H/L series logic technology with inverted output capabilities. It is housed in a CDIP16 package, designed for robust performance in demanding environments.

Feature Summary

Dual positive-edge-triggered D-type flip-flop architecture
Independent data, clock, preset, and clear control inputs
Complementary Q and not-Q outputs for versatile logic interfacing
Military-grade qualification under MIL-PRF-38535 standards

Applications

Military aerospace digital systems requiring high reliability
Data storage and shift register circuits in harsh environments
Timing and synchronization logic in defense communication equipment

Procurement Notes

Verify the specific suffix W/B against official manufacturer documentation to confirm package type and military qualification status. Ensure the component meets current environmental compliance requirements for your application. Cross-reference the lot code and date code with authorized distributors to guarantee authenticity and traceability before finalizing procurement.

Selection Notes

Select this component when dual D-type flip-flops with military temperature range operation are required. It is suitable for designs needing positive-edge triggering and asynchronous preset/clear functions. Consider the CDIP16 package constraints for board layout. Verify compatibility with existing TTL logic voltage levels and signal integrity requirements in the target system.

Part Context

This part belongs to the SN54L74 family of dual D-type flip-flops. Rochester Electronics provides these components as qualified replacements for original manufacturers. The '54' prefix indicates military grade performance, while 'L' denotes low-power TTL logic. The device supports critical applications where standard commercial parts may not suffice due to environmental or reliability demands.
