74HC85PW,118

Overview

The Nexperia 74HC85PW,118 is a 4-bit magnitude comparator integrated circuit manufactured by Nexperia USA Inc. It operates within a supply voltage range of 2 V to 6 V and features active high outputs indicating A<B, A=B, or A>B conditions. The device is housed in a 16-pin TSSOP package suitable for surface mount technology. It supports low power consumption with a maximum supply current of 8 uA and provides output drive currents of ±5.2 mA. The component functions reliably across an extended temperature range from -40°C to +125°C.

Feature Summary

• Performs 4-bit magnitude comparison between two binary inputs
• Provides active high logic outputs for less than, equal to, and greater than relationships
• Supports cascading operations for multi-bit expansion

Applications

• Digital arithmetic logic units requiring subtraction or comparison
• Address decoding systems in microcontroller interfaces
• Data validation circuits checking equality of digital words

Procurement Notes

Verify the specific suffix 118 corresponds to the TSSOP-16 package configuration when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the ordering part number matches the exact pinout and electrical specifications required for the target design. Cross-reference datasheet revisions to confirm any recent manufacturing changes.

Selection Notes

Select this component when a 4-bit magnitude comparator with active high outputs is required. The HC series offers standard CMOS performance compatible with various logic families. Consider the TSSOP-16 package constraints regarding PCB space and thermal dissipation. Verify that the 2V to 6V operating voltage range aligns with the system power supply rails.

Part Context

This part belongs to the 74HC family of high-speed CMOS logic devices produced by Nexperia. The 74HC85 specifically implements magnitude comparison functionality. It is distinct from XOR gates like the 74AHC86, serving a different logical purpose within digital circuit designs. The PW suffix indicates the plastic TSSOP housing type used for surface mounting.

Replacement Considerations

Equivalent parts include other manufacturers' 74HC85 variants in TSSOP-16 packages. Verify pin compatibility and electrical parameters before substitution. Generic 74HC85 components may serve as alternatives if they meet the same voltage and current specifications.
