SN74AS885NT3

Comparators Overview

The SN74AS885NT3 is an 8-bit magnitude comparator from Texas Instruments' AS series. It features true outputs and operates within a standard industrial temperature range of 0°C to 70°C. The device utilizes a 24-pin PDIP package with plastic/epoxy body material. Key electrical characteristics include a maximum supply current (ICC) of 85 mA and a load capacitance (CL) of 50 pF. It is designed for high-speed digital logic applications requiring precise bit-wise comparison.

Comparators Feature Summary

• Provides 8-bit magnitude comparison functionality with true output polarity
• Supports live insertion via power-off disable outputs
• Includes triple output enable, clear, and preset functions

Comparators Applications

• Digital data processing systems
• Address decoding circuits
• Comparator-based control logic

Comparators Procurement Notes

Verify RoHS compliance status as the component is listed as non-compliant in some sources. Confirm package type is PDIP-24 and check for tape-and-reel packaging suffix 'T3'. Ensure sourcing from authorized distributors to guarantee authenticity and proper handling specifications.

Comparators Selection Notes

Select this component when 8-bit unsigned integer comparison is required in AS series logic designs. Consider the 85 mA max ICC for power budgeting. Verify that the 50 pF load capacitance meets system requirements. Check temperature range suitability for the specific operating environment.

Comparators Part Context

Part of the Texas Instruments SN74AS family, known for advanced Schottky technology offering higher speed than standard LS series. The SN74AS885 specifically addresses magnitude comparison needs in 8-bit configurations, complementing other bus drivers and comparators in the same logic family.

Comparators Replacement Considerations

Check for SN74AS885N (non-tape version) if reel packaging is not required. Verify compatibility with SN74LS885 for slower speed applications, noting significant performance differences between AS and LS series.
