Working Principles

The QS3VH384QG is designed based on CMOS technology, allowing bidirectional signal switching. It utilizes a combination of MOSFETs and control circuitry to enable or disable the channels based on the input control signals. When a channel is enabled, it allows the signal to pass through in either direction. The low on-resistance ensures minimal signal distortion, while the high off-isolation prevents interference between channels.
