Description
The STG6684 is a high-speed CMOS low voltage
dual analog SPDT (single pole dual throw) switch
or 2:1 multiplexer/de-multiplexer switch fabricated
in silicon gate C²MOS technology.
The STG6684 is designed to operate from 1.65 to
4.3 V, making this device ideal for portable
applications.
The SELn inputs are provided to control the
switch operation. The switch Sn is ON (connected
to common ports Dn) when the SELn input is held
low and OFF (high impedance state exists
between the two ports) when SELn is held high.
QFN10L (1.8 x 1.4 mm)
The switch Tn is “on” (connected to common port
Dn) when the SELn input is held high and “off”
(high impedance state exists between the two
ports) when SELn is held low.
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.
