CD74HC688M96

Comparators Overview

The CD74HC688M96 is an 8-bit identity comparator manufactured by Texas Instruments, designed for high-speed CMOS logic applications. It compares two 8-bit binary or BCD words to determine equality. The device features a low-active output that asserts when the inputs are identical (A=B). It operates within a supply voltage range of 2V to 6V and includes an output-enable input to control data flow. Packaged in a 20-SOIC surface-mount format, it supports operation temperatures from -55°C to +125°C with a maximum propagation delay of 29ns at 6V.

Comparators Feature Summary

• Performs 8-bit magnitude comparisons between two binary or BCD words
• Provides a single active-low output indicating input equality
• Includes an output-enable pin for controlling signal transmission

Comparators Applications

• Digital system address matching
• Data validation circuits
• Error detection logic

Comparators Procurement Notes

Verify the specific suffix M96 indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation. Ensure the SOIC-20 package dimensions match the target PCB footprint requirements before finalizing procurement orders.

Comparators Selection Notes

Select this component for designs requiring precise 8-bit equality checks in high-speed environments. Consider the HC series speed characteristics relative to HCT variants if TTL compatibility is required. Evaluate the wide operating temperature range for industrial applications.

Comparators Part Context

This part belongs to the Texas Instruments CD74HC family of high-speed CMOS logic devices. It serves as a digital comparator within the broader logic IC category, functioning alongside decoders and buffers in complex digital systems.

Comparators Replacement Considerations

The CD74HCT688EE4 is a documented substitute offering similar functionality in a PDIP-20 package. Verify interface compatibility and pinout alignment before substituting.
