Working Principles

The QS3VH126S1G8 is based on CMOS technology and operates as a bidirectional signal switch. It utilizes a combination of MOSFETs and control logic to enable or disable the flow of signals between its input and output channels. When the enable pin (EN) is activated, the corresponding channel becomes operational, allowing signals to pass through. Conversely, when the enable pin is deactivated, the channel is turned off, isolating the input and output.
