SN74HCS251DR TI Multiplexer | 16-SOIC | 8-Ch, 2V-6V, Schmitt-Trigger

Product Overview

The SN74HCS251DR is a high-speed CMOS 8-channel digital multiplexer from Texas Instruments, featuring Schmitt-trigger inputs for improved noise immunity. It selects one of eight data inputs based on the state of three select lines (S0, S1, S2) and provides both true and complementary outputs. The device operates over a wide supply voltage range of 2V to 6V, making it suitable for battery-powered and industrial applications. Housed in a 16-pin SOIC package, it offers a compact solution for data routing and signal selection.
