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 Inputs 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.
