STG3692
QFN16L (2.6mm x 1.8mm)
Description
The STG3692 is a high-speed CMOS low voltage
quad analog S.P.D.T. (single pole dual throw)
switch or 2:1 multiplexer/demultiplexer switch
fabricated in silicon gate C
designed to operate from 1.65 V to 4.3 V, making
this device ideal for portable applications.
The nSEL inputs are provided to control the
switch. The switch S1 is ON (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.
2
MOS technology. It is
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.
