CD54HCT112F3A

Overview

The CD54HCT112F3A is a military-grade J-K flip-flop from the HCT series, manufactured by Texas Instruments. It features two independent negative-edge triggered functions with complementary outputs in a 16-lead ceramic DIP package. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum frequency of 20 MHz at nominal supply. It is rated for an extended temperature range from -55 °C to 125 °C, ensuring reliability in harsh environments.

Feature Summary

Military-grade construction utilizing glass-sealed ceramic packaging for enhanced durability
High-speed CMOS logic technology compatible with TTL input levels
Dual independent J-K flip-flop functions with complementary output signals

Applications

Harsh environment digital data storage systems
Military-grade shift register applications
High-reliability counter circuits

Procurement Notes

Verify the specific suffix F3A indicates the correct ceramic DIP variant. Confirm military rating requirements against project specifications. Check datasheet for RoHS compliance status as indicated in source data. Ensure compatibility with existing PCB footprints for 16-lead DIP packages. Validate supply voltage constraints before integration.

Selection Notes

Select this component when military-grade reliability and high-speed performance are required simultaneously. The HCT series ensures compatibility with standard TTL logic families while offering CMOS power efficiency. Consider the ceramic package for superior thermal and mechanical stability compared to plastic alternatives in extreme conditions.

Part Context

This part belongs to the CD54HCT family, representing Texas Instruments' high-speed CMOS logic line designed for military and aerospace applications. The '54' prefix denotes military grade, distinguishing it from commercial '74' variants. It shares functional similarities with other HCT flip-flops but offers specific packaging and environmental ratings.

Replacement Considerations

Consider CD54HC112F3A for similar functionality without TTL input compatibility. CD54HCT112F3A is the direct equivalent within the same series. Verify pinout compatibility if substituting with non-HCT logic families.
