The STG3159 is a high-speed CMOS low voltage
single analog S.P.D.T. (Single Pole Dual Throw)
switch or 2:1 Multiplexer /Demultiplexer switch
fabricated in silicon gate C2MOS technology. It is
designed to operate from 1.65V to 4.3V, making
this device ideal for portable applications.

The device offers very low ON-Resistance (1Ω) at
VCC = 4.3V. The SEL inputs are provided to
control the switch. The switch S1 is ON (they are
connected to common Ports Dn) when the SEL
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 SEL input is held low
and OFF (high impedance state exists between
the two ports) when SEL 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.

Electrical ratings
Stressing the device above the rating listed in the “Absolute Maximum Ratings” table may
cause permanent damage to the device. These are stress ratings only and operation of the
device at these or any other conditions above those indicated in the Operating sections of
this specification is not implied. Exposure to Absolute Maximum Rating conditions for
extended periods may affect device reliability. Refer also to the STMicroelectronics SURE
Program and other relevant quality documents.
