Description

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.

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
