SN74AHC157NS TI Multiplexer | 2V-5.5V, 4-Channel, 2-Input

Product Overview

The SN74AHC157NS is a high-speed CMOS quad 2-input multiplexer from Texas Instruments. It selects one of two 4-bit data sources (A or B) based on the state of the select (S) input. The device features a common output enable (OE) input that forces all outputs to a low state when high. Operating from 2V to 5.5V, it is ideal for battery-powered and low-voltage applications. The SN74AHC157NS is offered in the SOIC-16 package (NS suffix) and is fully specified for industrial temperature ranges.
