Working Principles

FST3253QSC utilizes MOSFET-based switches to control the flow of signals. When an appropriate control voltage is applied, the corresponding channel connects the input and output terminals, allowing the signal to pass through. Conversely, when the control voltage is removed, the channel disconnects, preventing the signal from flowing.
