Working Principles

ISL43143IRZ operates based on the principle of a CMOS transmission gate. It utilizes MOSFET transistors to control the flow of signals between its input and output pins. When the enable pin is activated, the IC allows the input signal to pass through to the corresponding output pin. Conversely, when the enable pin is deactivated, the IC isolates the input from the output, preventing signal transmission.
