SN74HC257DT TI Multiplexer | 16-SOIC | 4-Channel, 2-to-1, 2V-6V

Product Overview

The SN74HC257DT from Texas Instruments is a high-speed CMOS quad 2-input multiplexer with common select and enable logic. It selects one of two 4-bit data sources based on the state of the select input (S). The device operates over a wide voltage range of 2V to 6V, making it suitable for battery-powered and industrial applications. The outputs are 3-state, allowing for bus-oriented systems. The SN74HC257DT is housed in a 16-SOIC package, offering a compact solution for data routing and signal selection.
