Description
The STG4158 is a high-speed CMOS low voltage single analog SPDT (single pole dual throw) switch or 2:1 multiplexer/ demultiplexer switch fabricated in silicon gate C2MOS technology. Designed to operate from 1.65 to 4.5 V, this device is ideal for portable applications. It offers low ON resistance (0.6 ) at VCC = 4.5 V ( typical TA = 25 C). The SEL input threshold is compatible to 1.8 V, and provides control to the switches.

The switch S1 is ON (connected to common port D) 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 (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. The SEL input has an integrated weak pull-down resistor to prevent SEL signal from floating. For low power consumption, the SEL input must be grounded. Power-off and over-voltage protection The STG4158 features power-off and overvoltage protection, enabling the device to be isolated during voltage fault events.
