STG5682
Low voltage dual SPDTswitch
with negative rail capability
Features
■Distortion-free negative signal throughput
down to VCC-5.5V
■Wide operating voltage range:
VCC (Opr) = 1.65V to 4.5V single supply
■Ultra low power dissipation:
ICC = 0.2µA (Max.) at tA = 85°C
■Low "ON" resistance VIN = 0V:
RON = 0.5Ω (max. tA = 25°C) at VCC = 4.3V
■4.3V tolerant and 1.8V compatible threshold on
digital control input at VCC = 1.65 to 3.0V
■Latch-up performance exceeds 300mA
(JESD 17)
■ESD performance exceeds JESD22
■2000-V human-body model (A114-A)
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 C2MOS 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.

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.
