SN74AHC157DR TI Multiplexer | 16-SOIC | 2V to 5.5V, 4-Channel 2-Input

Product Overview

The SN74AHC157DR from Texas Instruments is a high-speed CMOS quad 2-input multiplexer designed for 2V to 5.5V VCC operation. It selects one of two 4-bit data sources (A or B) based on the state of the select (S) input. The device features a common output enable (OE) input that, when high, forces all outputs to a high-impedance state. This multiplexer is ideal for data routing, signal gating, and bus-oriented applications in industrial, automotive, and communication systems.
