Notes:

1. Use all the Power Supply Pins: VDD1, VDD2, VSS1, VSS2 (Make sure that VSS1 and VSS2 Pins have the same voltage level.)

2. Power must be supplied to VDD1, Logic Input and VDD2 so that the device may be protected from any harm caused by latch up. Power must be

turned off in a reversed manner. Power ON. OFF sequences must be observed at all times, even during the transition period.
