CD74AC157E TI Multiplexer | 16-PDIP | 1.5V-5.5V, 4-Channel 2:1

Product Overview

The CD74AC157E from Texas Instruments is a high-speed CMOS quad 2-input multiplexer. It selects one of two 4-bit data sources based on the state of the select input (S). The device features non-inverting outputs and is designed for operation from 1.5V to 5.5V, making it suitable for battery-powered and low-voltage applications. The 16-pin PDIP package ensures easy prototyping and through-hole assembly.
