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

Ω) at VCC =4.5 V (

typical TA = 25 ºC). 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 over-

voltage protection, enabling the device to be

isolated during voltage fault events.
