HD74HC4051

8-Channel Analog Multiplexer Demultiplexer

Description

This device connects together the outputs of 8 switches, thus achieving an 8 Channel Multiplexer. The
binary code placed on the A, B, and C select lines determine which one of the eight switches in “on”, and
connects one of the eight inputs to the common output.

Features

• High Speed Operation

• Wide Operating Voltage

• Low Quiescent Supply Current
