CD74HC257E TI Multiplexer | 16-PDIP | 2V-6V, 8-Channel

Product Overview

The CD74HC257E from Texas Instruments is a high-speed CMOS quad 2-input multiplexer with 3-state outputs. It selects one of two 4-bit data sources based on the state of the select input (S). The device operates from 2V to 6V, making it suitable for battery-powered applications. The 3-state outputs allow connection to bus-oriented systems. The CD74HC257E is packaged in a 16-pin PDIP, ideal for through-hole PCB designs.
