DESCRIPTION
The STG3685 is an high-speed CMOS DUAL
ANALOG S.P.D.T. (Single Pole Dual Throw)
SWITCH or DUAL 2:1 Multiplexer/Demultiplexer
Bus Switch fabricated in silicon gate C

MOS
technology. It is designed to operate from 1.4V to
4.3V, making this device ideal for portable
applications.
It offers very low ON-Resistance (<0.5鈩? at
V
CC
=3.0V. The IN input is provided to control the
switches. The switches nS1 are ON (they are
connected to common Ports Dn) when the IN input
is held high and OFF (high impedance state exists
between the two ports) when IN is held low; the
switches nS2 are ON (they are connected to
common Ports Dn) when the IN 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鈥檚 available in the commercial
temperature range Flip-chip package with Epoxy
Protection.
