DESCRIPTION
The STG3699 is an 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

MOS technology. It is designed to operate from
1.65V to 4.3V, making this device ideal for
portable applications.
It offers very low ON-Resistance (<0.5
) at
V
CC
=3.0V. The nIN inputs are provided to control
the switches. The switches nS1 are ON (they are
connected to common Ports Dn) when the nIN
input is held high and OFF (high impedance state
exists between the two ports) when nIN is held
low; the switches nS2 are ON (they are connected
to common Ports Dn) when the nIN input is held
low and OFF (high impedance state exists
between the two ports) when IN 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. It's available in the
commercial temperature range in TSSOP and
QFN3x3mm package.
