Working Principles

The ISL43143IV-T operates based on the principles of solid-state switching. When the control signals applied to the IN1 and IN2 pins are in a specific state, the switch connects the NO pin to the COM pin, allowing the signal to pass through. Conversely, when the control signals change, the switch disconnects the NO pin from the COM pin, blocking the signal flow.
