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 V
CC
- GND = 3V,
a V
CC
- V
EE
of up to 13 V can be controlled; for V
CC
-V
EE
level differences
above 13V a V
CC
- GND of at least 4.5V is required).
These multiplexer circuits dissipate extremely low quiescent power
over the full V
CC
-GND and V
CC
- V
EE
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

This device contains protection circuitry to guard against damage due to high static voltages or electric fields.
However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this
high-impedance circuit. For proper operation, V
IN
and V
OUT
should be constrained to the range GND≤(V
IN
or
V
OUT
)≤V
CC
.
Unused digital pins must be tied to an appropriate logic voltage level (e.g., either GND or V
CC
). Unused
Analog I/O pins may be left open or terminated.
