CD54HC175F3A

Overview

The CD54HC175F3A is a high-speed CMOS logic device featuring four D-type flip-flops with a master reset. Manufactured by Texas Instruments, it utilizes silicon gate CMOS technology to achieve speeds comparable to low-power Schottky TTL while maintaining standard CMOS low power dissipation. The component operates within a supply voltage range of 2 V to 6 V and supports a wide operating temperature range from -55 °C to 125 °C. It is housed in a 16-lead ceramic dual-in-line package (CDIP) designed for military-grade reliability.

Feature Summary

• Integrates four independent D-type flip-flops with a common master reset input
• High-speed operation utilizing silicon gate CMOS technology
• Military-grade qualification supporting extended temperature ranges
• Compatible with standard CMOS logic families

Applications

• Military aerospace data processing systems
• Ruggedized industrial control logic storage
• High-reliability communication equipment registers

Procurement Notes

Verify the specific suffix F3A against the manufacturer's current datasheet to confirm package integrity and environmental compliance. Ensure the procurement channel provides traceability documentation required for military or aerospace applications. Confirm that the ceramic packaging matches the design specifications for thermal and mechanical stress resistance.

Selection Notes

Select this component when designing systems requiring robust data storage in extreme environments. The HC series offers speed advantages over standard 5400/7400 series devices. Consider the CDIP package for through-hole mounting in ruggedized enclosures where surface mount options are unsuitable for vibration resistance.

Part Context

This part belongs to the Texas Instruments 54HC family of high-speed CMOS logic integrated circuits. The 54-series designation indicates military-grade quality standards, distinguishing it from the commercial 74-series variants. It serves as a fundamental building block for sequential logic circuits requiring reliable state retention under harsh conditions.

Replacement Considerations

The SN74HC175APWR is a commercial equivalent but lacks military qualification. For direct pin-compatible replacements, verify the CD74HC175EE4 for plastic DIP versions. Cross-reference with other 54HC175 variants to ensure identical electrical characteristics and package dimensions.
