Working Principles

The QS3VH125S1G operates based on a combination of CMOS and BiCMOS technologies. It utilizes a control signal to enable or disable the bidirectional signal path between its input and output pins. When the control signal is active, the IC allows the signal to pass through in either direction. Conversely, when the control signal is inactive, the IC isolates the input and output pins, preventing any signal transmission.
