HD74HC4051
HD74HC4051 is 8-Channel Analog Multiplexer/Demultiplexer manufactured by Hitachi Semiconductor.
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 mon output.
Features
- High Speed Operation
- Wide Operating Voltage
- Low Quiescent Supply Current
