SN74AS08NSR

Overview

The SN74AS08NSR is a quadruple 2-input positive AND gate from the Texas Instruments SN74AS series. It operates within a supply voltage range of 4.5 V to 5.5 V and features a SOIC-14 surface-mount package. Key electrical parameters include a propagation delay of 4.5 ns, a low-level output current of 2 mA, and a high-level output current of -20 mA. The device supports an operating temperature range from 0°C to +70°C.

Feature Summary

• Contains four independent 2-input AND logic gates in a single integrated circuit
• Utilizes Advanced Schottky (AS) technology for high-speed switching performance
• Provides standard TTL-compatible input and output voltage levels

Applications

• Digital logic circuits requiring multiple AND operations
• Data routing and selection systems
• Control logic interfaces in industrial equipment

Procurement Notes

Verify the specific suffix 'NSR' corresponds to the SOIC-14 package and tape-and-reel packaging configuration. Confirm that the component meets the required RoHS compliance standards for your assembly process. Ensure the manufacturer is identified as Texas Instruments to guarantee authenticity and traceability of the SN74AS series specifications.

Selection Notes

Select this component when high-speed AND gating is required within the 5V logic family. The SN74AS series offers faster propagation delays compared to standard or ALS variants. Consider the SOIC-14 footprint constraints and the specific current drive capabilities necessary for the connected load conditions in the design.

Part Context

This part belongs to the SN74AS logic family, which represents the high-speed variant of the standard 7400 series. It is designed for applications demanding rapid signal processing while maintaining compatibility with existing TTL logic levels. The SN74AS08 specifically implements the fundamental AND function across four separate channels.
