TECHNICAL DATA
IW4053B
Analog Multiplexer Demultiplexer
High-Performance Silicon-Gate CMOS
The IW4053B 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

of up to 13 V can be controlled; for V

These multiplexer circuits dissipate extremely low quiescent power

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 IW4053B is a triple 2-channel multiplexer having three separate
digital control inputs, A, B, and C, and an enable input. Each control input
selects one of a pair of channels which are connected in a single-pole
double-throw configuration.
