SN74LVC257D TI Multiplexer | 4-Ch 2-to-1 | 1.65-3.6V, 3-State Output

Product Overview

The SN74LVC257D from Texas Instruments is a quad 2-to-1 data selector/multiplexer with 3-state outputs. It operates over a wide supply voltage range of 1.65V to 3.6V, making it suitable for low-voltage applications. The device features four independent multiplexers, each selecting one of two data inputs (A or B) based on the common select input (S). The outputs can be disabled via the output enable (OE) input, placing them in a high-impedance state. This device is designed for high-speed data routing and is compatible with TTL levels.
