WAS4759
2.5Ω Dual SPDT Analog Switch with True
Isolation in Power-Down Mode, VCC=0
WAS4759
Http//:www.willsemi.com
Descriptions
The WAS4759 is a dual single-pole double-throw
(SPDT) analog switch that is designed to operate from
a single power supply (+2.3V to +5.5V). The device
offers low ON-state resistance and excellent ON-state
resistance matching with break-before-make feature,
to prevent signal distortion during the transferring of a
signal from one channel to another. The device is
capable of truly isolation in power-down mode, VCC=0
and signal pins are able to withstand voltage up to 8V.
As signal pins’ voltage is higher than VCC, very little
current will flow back to the supply. These features
make this device suitable for isolating Base-Band from
independent audio drivers, Class D or K and such
circumstance as power-up after signals are being
available.

Pin configuration (Top view)
The INx control pin has overvoltage protection that
allows voltages above VCC, up to 5.5V to be present
on the pin without damage or disruption of operation of
the part, regardless of the operating voltage. The
WAS4759 is also featured with smart circuitry to
minimize VCC leakage current even when INx control
voltage is lower than VCC supply voltage.
The WAS4759 is available in QFN2116-10L and
QFN1418-10L package. Standard product is Pb-Free
and halogen-Free.
