IW4052B
Analog Multiplexer Demultiplexer
High-Performance Silicon-Gate CMOS
The IW4052B analog multiplexer/demultiplexer is digitally controlled
analog switches having low ON impedance and very low OFF leakage
current. Control of analog signals up to 20V peak-to-peak can be
achieved by digital signal amplitudes of 4.5 to 20V (if V

independent of the logic state of the control signals. When a logic “1”is
present at the ENABLE input terminal all channels are off.
The IW4052 is a differential 4-channel multiplexer having two binary
control inputs. A and B, and an enable input. The two binary input signals
select 1 of 4 pairs of channels to turned on and connect the analog inputs
to the outputs.
