STG5682

Low voltage dual SPDTswitch

with negative rail capacitance

QFN16L (2.6mm x 1.8mm)

Description

The STG5682 is a high-speed CMOS low voltage
dual analog S.P.D.T. (Single Pole Dual Throw)
SWITCH or 2:1 Multiplexer /Demultiplexer Switch
fabricated in silicon gate C

2

MOS technology. It is
designed to operate from 1.65V to 4.5V, making
this device ideal for portable applications.

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.

STG5682 Maximum rating

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.
