SN74HC257DE4 TI Multiplexer | 16-SOIC | 4-Channel, 2-to-1

Product Overview

The SN74HC257DE4 is a high-speed CMOS quad 2-to-1 line data selector/multiplexer from Texas Instruments. It features four independent 2-input multiplexers that select one of two data sources (A or B) for each output (Y). The device operates from a 2V to 6V supply voltage, making it suitable for a wide range of digital applications. Packaged in a 16-pin SOIC, it offers low power consumption and high noise immunity.
