SN74LVC257AD TI Multiplexer | 16-SOIC | 4-Channel, 2:1, 3.3V

Product Overview

The SN74LVC257AD from Texas Instruments is a high-performance, 4-channel, 2:1 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 select (S) input. The outputs are 3-state, allowing connection to a common bus. The SN74LVC257AD is designed for high-speed data routing and signal gating in digital systems.
