CD74HC688M96E4

Comparators Overview

The CD74HC688M96E4 is an 8-bit identity/magnitude comparator from Texas Instruments, housed in a 20-SOIC package. It operates on a supply voltage range of 2 V to 6 V and supports an operating temperature range of -55°C to +125°C. The device features active-low outputs for A=B comparison and includes an enable function. Propagation delays are specified at 44 ns typical for the HC series.

Comparators Feature Summary

• Performs 8-bit magnitude and identity comparisons between two binary words
• Provides active-low output signals when input conditions are met
• Includes an enable pin to control comparator operation

Comparators Applications

• Embedded systems requiring data validation
• Industrial automation control logic
• Digital circuit address decoding

Comparators Procurement Notes

Verify the specific suffix M96E4 corresponds to the SOIC-20 package and reel/cut-tape packaging configuration. Confirm RoHS compliance status and lead times directly with authorized distributors or Texas Instruments, as availability may vary by region and production cycle.

Comparators Selection Notes

Select this component when an 8-bit comparator with active-low outputs and enable functionality is required within a 2V to 6V supply range. Ensure the SOIC-20 package fits the PCB layout constraints. Consider propagation delay specifications relative to system clock speeds to ensure timing compatibility.

Comparators Part Context

This part belongs to the CD74HC688 family of high-speed CMOS logic comparators. It is designed for general-purpose digital applications requiring reliable magnitude comparison. The device integrates standard TTL-compatible inputs with CMOS performance characteristics.

Comparators Replacement Considerations

Check for CD74HC688 variants with different packaging or suffixes. Verify electrical compatibility before substituting with other 8-bit comparators from Texas Instruments or third-party manufacturers.
