74HC151 IC Data Selector/Multiplexer DIP-16 74151

Product Overview

The 74HC151 is a high-speed CMOS 8-input multiplexer that selects one of eight binary data inputs (I0 to I7) and routes it to complementary outputs (Y and Y-bar) based on the logic levels applied to three select inputs (S0 to S2). An active-LOW enable input (E-bar) is provided; when E-bar is HIGH, the output Y is forced LOW and Y-bar is forced HIGH, regardless of the other inputs.
