STG3682
Low voltage high bandwidth dual SPDT switch
Features
■ Ultra low power dissipation:
– ICC = 0.2µA (Max.) at TA = 85°C
■ Low “ON” resistance:
– RON = 4.6Ω (TA = 25°C) at VCC = 4.3V
– RON = 5.8Ω (TA = 25°C) at VCC = 3.0V
■ Wide operating voltage range:
– VCC (Opr) = 1.65V to 4.3V single supply
■ 4.3V tolerant and 1.8V compatible threshold on
digital control input at VCC = 2.3V to 3.0V
■ Typical bandwidth (-3dB) at 800MHz on all
channels
■ Latch-up performance exceeds 100mA per
JESD 78, Class II
■ ESD performance exceeds JESD22
– 2000-V Human body model (A114-A)
■ USB (2.0) High speed (480Mbps) signal
switching compliant

Description
The STG3682 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 4.3V, making
this device ideal for portable applications.
The nSEL inputs are provided to control the
switch. The switch S1 is ON (they are connected
to common Ports Dn) when the nSEL input is held
high and OFF (high impedance state exists
between the two ports) when SEL is held low; the
switch S2 is ON (it is connected to common Port
D) when the nSEL input is held low and OFF (high
impedance state exists between the two ports)
when nSEL is held high.
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.

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.
