SN74HC251DR TI Multiplexer | 16-SOIC | 8-Ch, 2V-6V

Product Overview

The SN74HC251DR from Texas Instruments is a high-speed CMOS 8-input multiplexer with three-state outputs. It selects one of eight binary data sources and routes it to the output, controlled by three address lines (A, B, C). The device features an active-low output enable (OE) for bus-oriented applications. Operating from 2V to 6V, it is ideal for battery-powered and industrial systems.
