Low voltage dual SP4T switch
QFN16L (2.6 x 1.8 mm)
Description
The STG3482 is a high-speed CMOS low voltage
dual analog SP4T (single pole four throw) switch
or 4:1 multiplexer/demultiplexer switch fabricated
in silicon gate C
to operate from 1.65 to 4.3 V, making this device
ideal for portable applications.

By controlling the SEL1 and SEL2, one of the
independent channels will be connected to the
common channel. An /OE pin is also available in
this device to disconnect all the switches.
Additional key features are fast switching speed,
break-before-make delay time and ultra low power
consumption. All inputs and outputs are equipped
with protection circuits against static discharge,
giving them ESD immunity and transient excess
voltage.

3 Maximum rating
Stressing the device above the rating listed in the “Absolute maximum ratings” table may
cause permanent damage to the device. These are stress ratings only and operation of the
device at these or any other conditions above those indicated in the Operating sections of
this specification is not implied. Exposure to absolute maximum rating conditions for
extended periods may affect device reliability. Refer also to the STMicroelectronics SURE
Program and other relevant quality documents.
