SN74HC257N TI Multiplexer | 16-PDIP | 4-Channel, 2-Input, Non-Inverting

Product Overview

The SN74HC257N from Texas Instruments is a high-speed CMOS quad 2-input multiplexer with non-inverting outputs. It selects one of two 4-bit data sources (A or B) based on the select input (S). The device features a common output enable (OE) input that forces all outputs to the high-impedance state when high. Operating from 2V to 6V, it is ideal for bus-oriented systems requiring low power and high noise immunity.
