SN74LVC257ANSR TI Multiplexer | 16-SO | 4-Channel, 2-to-1, 3.3V

Product Overview

The SN74LVC257ANSR from Texas Instruments is a high-performance, 4-channel, 2-to-1 data multiplexer with 3-state outputs. It operates from 1.65V to 3.6V, making it ideal for low-voltage applications. The device features a standard '257 logic function, selecting one of two 4-bit data sources under control of a common select input. The 3-state outputs allow for bus-oriented systems. Housed in a 16-pin SO package, it offers a compact solution for data routing in modern electronics.
