MM74HC688MTCX

Comparators Overview

The MM74HC688MTCX is an 8-bit magnitude comparator from onsemi's HC logic family, housed in a 20-pin TSSOP package. It compares two 8-bit binary words and provides active-low outputs indicating equality (A=B), greater than (A>B), or less than (A<B). The device operates within a supply voltage range of 2V to 6V and supports a wide operating temperature range from -40°C to +85°C. It features low static power consumption typical of CMOS technology and is designed for surface-mount assembly.

Comparators Feature Summary

• Performs parallel comparison of two 8-bit binary numbers
• Provides distinct active-low status outputs for equality, greater-than, and less-than conditions
• Operates across a broad supply voltage range suitable for various digital systems

Comparators Applications

• Digital address decoding circuits
• Data validation and error checking modules
• Comparator-based control logic in embedded systems

Comparators Procurement Notes

Verify the specific suffix MTCX corresponds to the TSSOP-20 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design compatibility with the specified voltage and temperature ranges for the target application environment.

Comparators Selection Notes

Select this component when an 8-bit magnitude comparison function is required in a compact surface-mount form factor. Consider the HC logic series for standard CMOS performance and voltage compatibility. Evaluate pin count and package dimensions against available PCB real estate constraints during the design phase.

Comparators Part Context

This part belongs to the MM74HC series, representing high-speed CMOS logic devices. The 74HC688 specifically implements the magnitude comparator function defined in standard logic families. It serves as a digital building block for arithmetic and logical operations in integrated circuit designs.

Comparators Replacement Considerations

Check for equivalent parts from other manufacturers offering identical pinouts and electrical characteristics. Verify that any substitute maintains the same 20-TSSOP package and 8-bit comparator functionality without requiring schematic modifications.
