4051 IC "Single 8-Channel Multiplexer / Demultiplexer"

The 4051 device is a monolithic integrated circuit fabricated in MOS (metal oxide semiconductor) technology available in SO-16 and PDIP-16 packages. The 4051 analog multiplexer/demultiplexer is a digitally controlled analog switch having low ON impedance and very low OFF leakage current. This multiplexer circuit dissipates extremely low quiescent power over the full VDD – VSS and VDD – VEE supply voltage range, independent of the logic state of the control signals. This device is a single 8-channel multiplexer having three binary control inputs, A, B, and C, and an inhibit input. The three binary signals select 1 of 8 channels to be turned on, and connect one of the 8 inputs to the output. When a logic ?1? is present at the inhibit input terminal all channels are off.
