CD74AC257E TI Multiplexer | 16-PDIP | 1.5V-5.5V, 4-Channel 2:1

Product Overview

The CD74AC257E from Texas Instruments is a high-speed CMOS quad 2-input multiplexer with non-inverting outputs. It operates over a wide voltage range of 1.5V to 5.5V, making it suitable for battery-powered and low-voltage applications. The device features four independent 2-input multiplexers that select one of two data inputs (A or B) based on the common select input (S). The outputs are enabled by an active-low output enable (OE) input. The CD74AC257E is offered in a 16-pin PDIP package, ensuring easy integration into through-hole PCB designs.
