SN74ALS251D TI Multiplexer | 16-SOIC | 8:1, 3-State Output

Product Overview

The SN74ALS251D is a high-performance 8-input multiplexer with 3-state outputs from Texas Instruments. It selects one of eight binary data sources and routes it to a single output, controlled by three select lines (A, B, C). The device features a strobe (G) input that, when high, forces the output into a high-impedance state, enabling bus-oriented applications. Fabricated with advanced Schottky-clamped bipolar technology, it offers a typical propagation delay of 8 ns and low power consumption of 19 mW per gate. The SN74ALS251D is housed in a 16-pin SOIC package, ideal for space-constrained designs.
