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 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.

TA = -55° to 125° C for all packages
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.
