Maximum ratings

Stressing the device above the rating listed in the “absolute maximum ratings” table may

cause permanent damage to the device. These are stress ratings only and operation of the

device at these or any other conditions above those indicated in the operating sections of

this specification is not implied. Exposure to absolute maximum rating conditions for

extended periods may affect device reliability.

1. This parameter applies when the start-up current source is OFF. This is the case when the VDD voltage

has reached VDDon and remains above VDDoff.

2. This parameter applies when the start up current source is on. This is the case when the VDD voltage has

not yet reached VDDon or has fallen below VDDoff.
