SN74AS158NSR

Overview

The SN74AS158NSR is a quad 1-of-2 data selector/multiplexer from Texas Instruments' AS logic series. It operates within a supply voltage range of 4.5 V to 5.5 V and features a propagation delay of 4.5 ns. The device supports surface-mount installation in a 16-pin SOIC package and functions reliably across an operating temperature range of 0°C to +70°C.

Feature Summary

• Integrates four independent 1-of-2 data selectors within a single integrated circuit
• Delivers high-speed signal routing with a propagation delay of 4.5 ns
• Compatible with standard TTL logic families for seamless system integration

Applications

• High-speed digital data routing systems
• Signal path selection in communication equipment
• Logic control circuits requiring rapid multiplexing

Procurement Notes

Verify the specific suffix 'NSR' confirms the reel packaging format and SOIC-16 footprint. Ensure the component matches the AS logic family specifications rather than AHCT or ALS variants. Confirm RoHS compliance status through official manufacturer documentation prior to final procurement decisions.

Selection Notes

Select this component when high-speed switching capabilities are required alongside standard TTL compatibility. The AS series offers superior speed compared to standard 74LS devices while maintaining pin-out compatibility. Evaluate thermal management requirements given the operational temperature limits and power dissipation characteristics inherent to the AS logic family.

Part Context

This part belongs to the SN74AS158 series, representing advanced Schottky TTL technology. It serves as a high-performance alternative to slower logic families, designed for applications demanding rapid data selection without compromising signal integrity. The NSR designation indicates a tape-and-reel manufacturing configuration suitable for automated assembly processes.
