## Description

The SN74ALS158 is a digital multiplexer IC from Texas Instruments, part of the ALS (Advanced Low-power Schottky) family. This component functions as a quadruple 1-of-2 data selector, meaning it can select one of two input sources for each of its four output channels. The configuration is 2:1, and it features buffered inputs and outputs.

Designed for digital logic applications, the SN74ALS158 operates over a commercial temperature range of 0°C to 70°C. It is available in various package options including Plastic Small-Outline (SOP), SOIC, and PDIP. The device includes a separate strobe input (G\) for data selection control. The SN74ALS158 presents inverted data to the outputs, which helps minimize propagation delay time compared to its true-data counterparts.

This multiplexer is suitable for applications requiring efficient data routing and selection within digital systems. Its ALS technology offers a balance of speed and low power consumption. The buffered outputs ensure signal integrity when driving subsequent logic stages.
