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. Due to the SCR structure inherent in the CMOS process used to fabricate these devices, connecting any terminal to a voltage greater
than V
DD
or less than V
SS
may cause destructive device latchup. For this reason it is recommended that the power supply to the device
be established before any inputs are applied and that in multiple systems the supply to the ICM7217 be turned on first.
2.
θ

is measured with the component mounted on an evaluation PC board in free air.
