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 VCC - GND = 3V, a VCC - VEE of up to 13 V can be controlled; for VCC - VEE level differences above 13V a VCC - GND of at least 4.5V is required).

These multiplexer circuits dissipate extremely low quiescent power over the full VCC -GND and VCC - VEE supply-voltage ranges, 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.
