Overview
The STG3856QTR is a high-speed CMOS low voltage dual analog SP3T (single pole triple throw) switch or dual 3:1 multiplexer/demultiplexer switch, fabricated in silicon gate C2MOS technology. It is designed to operate from 1.65 V to 4.3 V, making it ideal for portable applications. The device offers very low ON resistance and fast switching speeds, along with ultra-low power consumption. All inputs and outputs are equipped with protection circuits against static discharge, providing ESD immunity and transient excess voltage protection.
