SN74ALS158DRE4

Overview

The SN74ALS158DRE4 is a quad 2-line to 1-line data selector/multiplexer from Texas Instruments' ALS logic series. It features four independent multiplexers in a 16-pin SOIC package. Key electrical parameters include a propagation delay of 14 ns, operating voltage range of 4.5 V to 5.5 V, and an operating temperature range of 0°C to +70°C.

Feature Summary

• Provides four independent 2-to-1 data selection paths within a single integrated circuit.
• Utilizes Advanced Low-power Schottky (ALS) technology for high-speed operation with reduced power consumption.
• Designed for surface-mount installation using the standard 16-pin SOIC narrow package format.

Applications

• Data routing in digital communication systems
• Address decoding circuits
• Signal switching in industrial control panels

Procurement Notes

Verify the specific suffix 'RE4' indicates tape-and-reel packaging configuration distinct from tube-packaged variants like 'D'. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure supply chain sources provide valid traceability for this specific reel-based component variant.

Selection Notes

Select this component when designing systems requiring low-power Schottky speed characteristics with surface-mount constraints. Compare against HC or HCT series if lower voltage operation is required, as this ALS device mandates a strict 4.5V to 5.5V supply range. Verify pin compatibility with existing PCB footprints for 16-SOIC packages.

Part Context

This part belongs to the SN74ALS158 family of quadruple multiplexers. It serves as a high-speed alternative to standard 74LS158 devices, offering faster switching times while maintaining compatible logic levels. The RE4 suffix specifically denotes the reel packaging method used for automated assembly processes.

Replacement Considerations

SN74ALS158D is a tube-packaged equivalent with identical electrical specifications. SN74S158 offers similar functionality but may differ in power consumption profiles. Verify pinout compatibility before substituting with non-TI manufacturers.
