SN74HC257NSR TI Multiplexer | 16-SO | 4-Channel, 2-Input, 5V

Product Overview

The SN74HC257NSR from Texas Instruments is a high-speed CMOS quad 2-input multiplexer with common select and enable inputs. It selects one of two 4-bit data sources based on the state of the select input (S). The device features non-inverting outputs and a common output enable (OE) input. When OE is high, all outputs are in the high-impedance state. The SN74HC257NSR is designed for operation from 2V to 6V, making it suitable for a wide range of digital applications.
