SN74LVC257ADR TI Multiplexer | 16-SOIC | 3.3V, 4-Channel 2:1

Product Overview

The SN74LVC257ADR from Texas Instruments is a high-performance quad 2-line to 1-line data selector/multiplexer with 3-state outputs. Designed for 2.7V to 3.6V VCC operation, it is ideal for low-voltage, high-speed applications. The device features four multiplexers, each selecting one of two data inputs (A or B) based on the select (S) input. The outputs are 3-state, allowing connection to bus-oriented systems. The SN74LVC257ADR is housed in a 16-pin SOIC package, offering a compact solution for space-constrained designs.
