Overview
The STG3682QTR is a high-speed CMOS low voltage dual analog S.P.D.T. (Single Pole Dual Throw) Switch or 2:1 Multiplexer/Demultiplexer Switch fabricated in silicon gate C2MOS technology. It is designed to operate from 1.65V to 4.3V, making this device ideal for portable applications. The switch is controlled by the nSEL inputs, allowing for flexible switching between two channels.
