Working Principles

The TC7W66FK,LF is based on CMOS technology, which allows it to operate at low voltages while providing fast switching speeds. The device consists of two independent analog switches controlled by the IN1 and IN2 inputs. When the control input is high, the corresponding switch is turned on, allowing the signal to pass from the input to the output. Conversely, when the control input is low, the switch is turned off, isolating the input from the output.
