CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation
of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
NOTES:
1. Destructive latchup may occur if input signals are applied before the power supply is established or if inputs or outputs are forced to
voltages exceeding VDD or VSS by 0.3V.
2. θJA is measured with the component mounted on an evaluation PC board in free air.
