The STG3220 is a high-speed CMOS low voltage dual analog SPDT (single pole dual throw) switch or 2:1 multiplexer/de-multiplexer switch fabricated in silicon gate C2MOS technology.
The STG3220 is a high-speed CMOS low voltage dual analog SPDT switch or 2:1 multiplexer designed for portable applications. It operates from a supply voltage of 1.65 V to 4.3 V and features an ultra-low power dissipation of 1 µA maximum at 85 °C. The device includes an integrated fail-safe function to withstand over-voltage conditions when powered off and an interrupt function to indicate dedicated port charging mode.
