Analog Multiplexer Demultiplexer

High-Performance Silicon-Gate CMOS

The SL4051B 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 V
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 SL4051B is a single 8-channel multiplexer having three binary
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.

• Operating Voltage Range: 3.0 to 18 V

• Maximum input current of 1 µA at 18 V over full package-
