DESCRIPTION
The STG3157 is an high-speed spdt CMOS
ANALOG S.P.D.T. (Single Pole Dual Throw)
SWITCH or 2:1 Multiplexer/Demultiplexer Bus
Switch fabricated in silicon gate C²MOS
tecnology. It designed to operate from 1.65V to
5.5V, making this device ideal for portable
applications.
It offers very low ON-Resistance (<9Ω) at
V_CC=3.0V. The IN input is provided to control the
S.P.D.T. switch, it’s compatible with standard
PIN CONNECTION AND IEC LOGIC SYMBOLS

CMOS output. The switch S1 is ON (it is
connected to common Port D) when the IN input is
held high and OFF (high impedance state exists
between the two ports) when IN is held low; the
switch S2 is ON (it is connected to common Port
D) when the IN input is held low and OFF (high
impedance state exists between the two ports)
when IN is held high. Additional key faetures are
fast switching speed, Break Before Make Delay
Time and Very Low Power Consumption. All
inputs and output 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 smallest six lead smd package on the market.
