TECHNICAL DATA
IW4051B
Analog Multiplexer Demultiplexer
High-Performance Silicon-Gate CMOS
The IW4051B 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 IW4051B 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
