SN74F257DR TI Multiplexer | 16-SOIC | 4-Ch, 2-Input, Non-Inverting

Product Overview

The SN74F257DR is a high-speed quad 2-input multiplexer from Texas Instruments, designed for data selection and routing in digital systems. It features four independent multiplexers, each with two data inputs (A and B) and a common select input (S). The outputs are non-inverting and provide the selected data when the output enable (OE) is low. This device is fabricated using advanced Schottky bipolar technology, offering fast propagation delays and low power consumption. It is housed in a 16-pin SOIC package, suitable for surface-mount applications.
