SN74LVC257ADB TI Multiplexer | 16-SSOP | 4-Channel, 2-Input, 3.3V

Product Overview

The SN74LVC257ADB 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 multiplexers, each selecting one of two data inputs based on the select input (S). The outputs are enabled by an output enable (OE) input, allowing for bus-oriented applications. The SN74LVC257ADB is housed in a 16-pin SSOP package, offering a compact solution for space-constrained designs.
