SL4052B
Analog Multiplexer Demultiplexer
High-Performance Silicon-Gate CMOS
The SL4052B 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

- GND = 3V, a

of up to 13 V can be controlled; for V

level differences
above 13V a V

These multiplexer circuits dissipate extremely low quiescent power
over the full V

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 SL4052 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.
