SN74S251N TI Logic Multiplexer | 3-State, 8-Input, Schottky

Product Overview

The SN74S251N is a high-speed 8-input multiplexer with 3-state outputs from Texas Instruments, featuring Schottky-clamped transistors for improved performance. It selects one of eight data sources as determined by the address inputs (A0, A1, A2). The device includes an active-low enable input (G) and an active-low output enable (OE) for bus-oriented applications. The 3-state outputs allow connection to a common bus line, providing high impedance when disabled. This IC is ideal for data routing, signal selection, and bus multiplexing in digital systems.
