74HC151D is 8-Channel Multiplexer. A multiplexer, often abbreviated as “mux,” is an electronic device or integrated circuit (IC) used in digital and analog electronics to select one of several input signals and route it to a single output. It functions like a data selector, allowing you to choose which input signal is passed through to the output based on a control signal. Multiplexers are essential components in various electronic systems and are used for a wide range of applications.

This is a high speed CMOS 8-CHANNEL MULTIPLEXER fabricated with silicon gate C2MOS technology. It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. One of eight date input signals (D0-D7) is selected by decoding of the three-bit address input (A, B, C). The selected data appears on two outputs: non-inverting (Y) and inverting (W). The strobe input provides two output conditions; a low level on the strobe input transfers the selected data to the outputs. A high level on the strobe input sets the Y output low and the W output high without regard to the data or select input conditions.
