SN74HC251N TI Multiplexer | 16-PDIP | 8-Channel, 3-State Output

Product Overview

The SN74HC251N is a high-speed CMOS 8-input multiplexer with 3-state outputs from Texas Instruments. It selects one of eight binary data inputs (D0–D7) based on the address inputs (A0–A2) and provides the selected data at the output (Y). The device features a strobe input (G) for enabling or disabling the output, and a 3-state output control (OE) for bus-oriented applications. Operating from 2V to 6V, it offers low power consumption and high noise immunity typical of HC family devices.
