SN74AS885DW

Comparators Overview

The SN74AS885DW is an octal magnitude comparator from Texas Instruments' AS logic series, housed in a 24-pin SOIC package. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range of 0°C to 70°C. The device features active-high outputs with a maximum low-level output drive current of 20 mA and a high-level output drive current of -2 mA.

Comparators Feature Summary

• Performs eight-bit magnitude comparison between two binary inputs
• Provides active-high status outputs for equality, greater-than, and less-than conditions
• Utilizes AS logic family technology for defined performance characteristics

Comparators Applications

• Digital data processing systems requiring magnitude evaluation
• Control logic circuits for numerical value verification
• Industrial instrumentation for signal comparison tasks

Comparators Procurement Notes

Verify the specific suffix 'DW' confirms the SOIC-24 package and commercial temperature grade (0°C to 70°C). Confirm the component matches the SN74AS885 functional specification rather than the SN54 variant. Ensure the source document explicitly lists this part number as production data or current information to validate availability status.

Comparators Selection Notes

Select this component when an octal comparator with active-high outputs is required for standard 5V logic applications. The AS series offers specific drive capabilities suitable for interfacing with various digital loads. Verify that the commercial temperature range meets the environmental requirements of the target system design.

Comparators Part Context

This part belongs to the SN74AS885 family of 8-bit magnitude comparators manufactured by Texas Instruments. The 'DW' designation specifically identifies the plastic small-outline integrated circuit (SOIC) package configuration. It is distinct from the SN54AS885, which is characterized for military-grade extended temperature ranges.
