Analog Multiplexer Demultiplexer

High-Performance Silicon-Gate CMOS

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

- GND = 3V, a V

required).

control inputs, A,B and C, and an ENABLE input. The three binary

signals select 1 of 8 channels to be turned on, and connect one of the 8

inputs to the output.

The IW4051B analog multiplexer/demultiplexer is digitally

These multiplexer circuits dissipate extremely low quiescent power

The IW4051B is a single 8-channel multiplexer having three binary
