The STG3820 device is a high-speed CMOS low voltage quad analog DPDT (dual pole dual throw) switch or 2:1 multiplexer/demultiplexer switch fabricated in silicon gate C2MOS technology. It is designed to operate from 1.65 V to 4.3 V, making this device ideal for portable applications.


The SELm-n input is provided to control the switches. The switches nS1 and mS1 are ON (connected to common ports Dn and Dm respectively) when the SELm-n input is held high and OFF (high impedance state exists between the two ports) when the SELm-n is held low. The switches nS2 and mS2 are ON (connected to common port Dn and Dm respectively) when the SELm-n input is held low and OFF (high impedance state exists between the two ports) when the SELm-n is held high.


The STG3820 device has an integrated fail safe function to withstand overvoltage condition when the device is powered off. Additional key features are fast switching speed, break-before-make-delay time and ultralow power consumption. All inputs and outputs are equipped with protection circuits against static discharge, giving them ESD immunity and transient excess voltage.
