CD74HCT670M96E4

Overview

The CD74HCT670M96E4 is a high-speed CMOS logic register file manufactured by Texas Instruments. It features a 4-by-4 architecture with four independent input and output lines, housed in a 16-pin SOIC package. The device operates on a single power supply ranging from 4.5 V to 5.5 V. It supports a propagation delay of 295 ns and provides an output current capability of 6 mA for both low and high states. The component functions within an extended temperature range from -55°C to +125°C.

Feature Summary

• High-speed CMOS technology ensures rapid signal processing capabilities.
• Integrated 4-by-4 register file structure manages data storage and transfer.
• Extended industrial temperature rating allows operation in harsh environments.

Applications

• Data buffering in digital communication systems
• Address latching in memory interface circuits
• General-purpose register applications in embedded controllers

Procurement Notes

Verify the specific suffix E4 indicates lead-free compliance and RoHS standards when sourcing. Confirm the SOIC-16 package dimensions match the target PCB footprint. Ensure the HCT logic family voltage requirements align with the system's 5V logic levels before finalizing procurement specifications.

Selection Notes

Select this component when a 4-bit wide register file is required with HCT-compatible input thresholds. The SOIC-16 surface-mount package facilitates automated assembly. Verify that the 4.5V to 5.5V operating range suits the design's power supply constraints and that the 295ns delay meets timing requirements.

Part Context

This part belongs to the Texas Instruments CD74HCT670 series of high-speed CMOS logic devices. It serves as a specialized register file within the broader 74HCT logic family, designed for applications requiring reliable data storage and retrieval in digital circuits. The E4 suffix typically denotes environmental compliance attributes.

Replacement Considerations

Compatible substitutes include the CD74HC670M96 for HC logic compatibility or the CD74HCT670E for PDIP packaging alternatives. Verify pinout and electrical characteristics match before substitution.
