SN74ALS251FN TI Multiplexer | 8-to-1, 3-State Output, ALS Logic

Product Overview

The SN74ALS251FN is a high-performance 8-input multiplexer with 3-state outputs from Texas Instruments, designed for data routing and selection in digital systems. It features advanced low-power Schottky (ALS) technology, providing a balance of speed and power efficiency. The device selects one of eight data sources based on the state of three select lines (A, B, C) and outputs the selected data through a 3-state buffer. The 3-state outputs allow connection to a common bus without loading the bus when disabled. The SN74ALS251FN is ideal for applications requiring high-speed data multiplexing with minimal power consumption.
