CD74HCT688MG4

Comparators Overview

The CD74HCT688MG4 is an 8-bit magnitude comparator manufactured by Texas Instruments in a 20-pin SOIC package. It operates within a voltage range of 4.5 V to 5.5 V, with a maximum propagation delay of 14 ns and a maximum supply current of 8 µA. The device supports through-hole or surface-mount installation and functions between -55°C and +125°C.

Comparators Feature Summary

• Provides active-low outputs for identity comparison (A = B)
• Supports cascading for multi-bit expansion
• Compatible with standard LSTTL loads

Comparators Applications

• Digital data comparison circuits
• Address decoding systems
• Error detection logic

Comparators Procurement Notes

Verify the exact suffix MG4 against the manufacturer's official datasheet to confirm pinout and electrical specifications. Ensure the component matches the required 20-SOIC package dimensions and RoHS compliance status before integration into production designs.

Comparators Selection Notes

Select this component when an 8-bit magnitude comparator with HCT logic compatibility is required. Consider the 20-SOIC package for surface-mount applications and verify that the 14 ns propagation delay meets system timing requirements.

Comparators Part Context

This part belongs to the Texas Instruments CD74HCT688 family of high-speed CMOS logic devices. It serves as an 8-bit magnitude comparator designed for digital systems requiring precise equality checking between two binary inputs.
