MM74HC688WMX

Comparators Overview

The MM74HC688WMX is an 8-bit magnitude comparator manufactured by onsemi, belonging to the 74HC logic family. It features a 20-pin SOIC surface-mount package and operates within a supply voltage range of 2V to 6V. The device provides active-low outputs indicating equality (A=B) between two 8-bit binary words. It supports a wide operating temperature range from -40°C to +85°C and utilizes CMOS input technology for low power consumption.

Comparators Feature Summary

• Performs parallel comparison of two 8-bit binary numbers
• Provides active-low output signal when inputs are equal
• Compatible with standard CMOS logic levels

Comparators Applications

• Digital address decoding systems
• Data validation circuits
• Equality checking in microprocessor interfaces

Comparators Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix 'WMX' corresponds to the required tape-and-reel packaging format. Ensure the procurement source provides valid traceability documentation. Check for RoHS compliance status as indicated in official datasheets. Validate that the supplier is an approved partner for onsemi products.

Comparators Selection Notes

Select this component for applications requiring precise 8-bit data comparison with active-low signaling. Consider the 74HC series characteristics for general-purpose digital logic interfacing. Evaluate the 20-SOIC package dimensions against available PCB real estate. Assess the 2V to 6V operating voltage range against system power rails. Review propagation delay specifications if timing constraints are critical.

Comparators Part Context

This part belongs to the MM74HC series of high-speed CMOS logic devices produced by onsemi. The MM prefix typically denotes specific manufacturing lines or packaging variants within the broader 74HC family. These components are designed for compatibility with standard TTL logic levels while offering improved speed and lower power consumption compared to older HC technologies.

Comparators Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided reference material. Verify pinout and electrical specifications before considering alternative manufacturers. Cross-reference with other 8-bit comparators from different vendors only after confirming functional equivalence.
