CAUTION: Stresses above those listed in âAbsolute Maximum Ratingsâ 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:
3. The ICM7216 may be triggered into a destructive latchup mode if either input signals are applied before the power supply is applied or if input
or outputs are forced to voltages exceeding VDD to VSS by more than 0.3V.
4. θJA is measured with the component mounted on an evaluation PC board in free air.
Electrical Specifications VDD = 5.0V, VSS = 0V, TA = 25oC, Unless Otherwise Specified
