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. 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 V
DD
to V
SS
by more than 0.3V.
2.
