SN74AS885DWR

Comparators Overview

The SN74AS885DWR is an 8-bit magnitude comparator manufactured by Texas Instruments in a 24-pin SOIC package. It operates within a supply voltage range of 4.5 V to 5.5 V and features active high outputs for A<B and A>B conditions. The device exhibits a maximum propagation delay of 17.5 ns at 5 V with a 50 pF load. It supports non-inverting polarity and is designed for surface mount installation.

Comparators Feature Summary

• Provides 8-bit magnitude comparison capabilities
• Delivers active high output signals for inequality detection
• Supports standard 5 V logic operation

Comparators Applications

• Digital data comparison circuits
• Address decoding systems
• Control logic verification

Comparators Procurement Notes

Verify the specific suffix DWR indicates tape and reel packaging configuration. Confirm the 24-SOIC package dimensions match board layout requirements. Ensure operating temperature ranges align with system environmental specifications before finalizing procurement orders.

Comparators Selection Notes

Select this component when 8-bit magnitude comparison is required with active high outputs. Consider the 17.5 ns propagation delay for timing constraints. Verify compatibility with 5 V logic families and ensure adequate thermal management for the SOIC-24 package in enclosed environments.

Comparators Part Context

This part belongs to the SN74AS series of advanced Schottky logic devices. It functions as a dedicated magnitude comparator rather than a general-purpose logic gate. The design follows standard TTL-compatible input levels while offering improved speed characteristics typical of the AS family compared to older variants.

Comparators Replacement Considerations

SN74ALS688DWR is an identity comparator variant. SN74AS885DR is the same device in a different package option.
