CD54HCT374F3A

Overview

The CD54HCT374F3A is a high-speed CMOS logic octal D-type flip-flop manufactured by Texas Instruments. It features three-state outputs and operates within a supply voltage range of 4.5 V to 5.5 V. The device is housed in a 20-lead ceramic dual in-line package (CDIP) designed for military-grade reliability. It supports an operating temperature range from -55°C to +125°C, ensuring functionality in extreme environments.

Feature Summary

Octal D-type flip-flop architecture with data enable control
Three-state outputs for bus-oriented memory applications
Military-grade ceramic packaging for harsh environment resilience

Applications

Bus-oriented memory register systems
High-reliability military communication equipment
Industrial control systems requiring wide temperature stability

Procurement Notes

Verify the specific suffix F3A indicates the correct ceramic package variant. Confirm military qualification status if required for your application. Check current availability as this component may have limited stock or be subject to long lead times due to its specialized nature. Ensure compatibility with existing board layouts for the 20-CDIP footprint.

Selection Notes

Select this component when an octal D-type flip-flop with three-state outputs is required for high-speed digital circuits. It is suitable for designs needing wide temperature operation and robust physical packaging. Consider alternatives like the HC series if lower power consumption is prioritized over speed, or if plastic packaging suffices for the environmental conditions.

Part Context

This part belongs to the Texas Instruments 54HCT logic family, which combines high-speed CMOS performance with TTL-compatible input levels. The 54-series designation typically denotes military-grade specifications, including extended temperature ranges and stricter manufacturing controls compared to commercial 74-series counterparts.

Replacement Considerations

Compatible substitutes include CD54HC374F3A for similar functionality with HC logic levels, and CD54HCT377F3A for octal flip-flops with different enable configurations. Verify pinout compatibility before substitution.
