74HC85PW,112

Comparators Overview

The Nexperia 74HC85PW,112 is a 4-bit magnitude comparator integrated circuit belonging to the 74HC logic family. It operates within a supply voltage range of 2 V to 6 V and features active high outputs for A<B, A=B, and A>B comparisons. The device is housed in a 16-pin TSSOP package and supports surface mount installation. It functions reliably across an extended temperature range from -40 °C to +125 °C with a maximum power consumption of 8 µA.

Comparators Feature Summary

• Performs 4-bit digital magnitude comparison between two input words
• Provides three distinct active high output signals for less than, equal, and greater than conditions
• Supports cascading operations for multi-bit expansion using dedicated cascade inputs

Comparators Applications

• Digital address decoding systems
• Data sorting and comparison circuits
• Magnitude evaluation in control logic

Comparators Procurement Notes

This component is classified as obsolete by the manufacturer. Production has ceased, and the factory is no longer accepting new orders. Availability is restricted to existing stock held by distributors or secondary market sources. Buyers should verify part authenticity and storage conditions carefully due to the end-of-life status.

Comparators Selection Notes

Engineers requiring this specific function must evaluate alternative components from current production lines. Modern replacements may offer updated packaging or improved electrical characteristics. Designers should review pin compatibility and logical equivalence before substituting to ensure circuit integrity without extensive redesign.

Comparators Part Context

The 74HC85 series represents a standard CMOS magnitude comparator widely used in legacy digital designs. The PW suffix indicates a plastic TSSOP package suitable for automated surface mount assembly. This specific variant integrates internal protection against electrostatic discharge, enhancing reliability in industrial environments.

Comparators Replacement Considerations

Verify functional equivalence with other 4-bit comparators such as the 74HC85PW,118 if available. Ensure that any substitute maintains identical pinout configuration and logic levels to facilitate direct replacement in existing PCB layouts.
