Mode Selection Pin 4 and Supply Voltage Pin 2
Zero Voltage Switch Operation
The operational modes can be selected by the external voltage at the synchronous input pin 4
(clamping). The mode selection determines the current requirement of the relay's or triac's driver
stage and hence the selection of the supply voltage.
