SN74LVC257ADT TI Multiplexer | 16-SOIC | 4-Channel, 2-Input, 3.3V

Product Overview

The SN74LVC257ADT from Texas Instruments is a high-performance quad 2-input multiplexer with 3-state outputs. It operates from 1.65V to 3.6V, making it ideal for low-voltage applications. The device features four independent multiplexers, each selecting one of two data inputs based on the common select input (S). The outputs are 3-state, allowing connection to bus-oriented systems. The SN74LVC257ADT is housed in a 16-pin SOIC package, offering a compact solution for data routing in digital systems.
