IW4053B
TECHNICAL DATA
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. 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 singlepole double-throw configuration.
