ELECTRICAL OPERATING CONDITIONS
Operating time: the circuit is designed to be able to operate continuously
Backup: no backup capability (standby) will be provided internally
Handling: inputs and outputs are protected against electrostatic discharge in normal handling. However, to be totally
safe, it is desirable to take normal handling precautions appropriate to handling MOS devices.
