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

These multiplexer circuits dissipate extremely low quiescent power

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-

temperature range; 100 nA at 18 V and 25

°C

• Noise margin (over full package temperature range):

1.0 V min @ 5.0 V supply

2.0 V min @ 10.0 V supply

2.5 V min @ 15.0 V supply
