CD54HC670F3A

Shift Registers Overview

The CD54HC670F3A is a high-speed CMOS register file manufactured by Harris Corporation. It features a 1-element, 4-bit architecture housed in a 16-lead ceramic dual in-line package (CDIP). The device operates within a supply voltage range of 2V to 6V and supports an operating temperature range from -55°C to 125°C. It is designed for simultaneous and independent read and write operations.

Shift Registers Feature Summary

• Supports simultaneous and independent read and write operations
• High-speed CMOS technology construction
• Military-grade temperature rating capability

Shift Registers Applications

• Data storage in digital systems
• Register file applications
• High-reliability military electronics

Shift Registers Procurement Notes

Verify the manufacturer origin, as Harris Semiconductor assets were acquired by Renesas Electronics. Confirm the specific suffix 'F3A' corresponds to the intended ceramic DIP variant and check for RoHS compliance status, which may be non-compliant for this legacy part number.

Shift Registers Selection Notes

Select this component when a single 4-bit register with independent access is required. Ensure the design accommodates the CDIP16 through-hole form factor and validates compatibility with the 2V to 6V supply voltage range for the target environment.

Shift Registers Part Context

This part belongs to the HC/UH series of logic devices. It functions as a shift register or register file element. The '54' prefix typically denotes military temperature range qualification, while 'HC' indicates high-speed CMOS technology.
