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.
NOTE:
1. Due to the SCR structure inherent in the CM0S 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 no inputs from sources operating on a different
power supply be applied to the device before its own supply is established, and when using multiple supply systems the supply to the ICM7218
should be turned on first.
2. _JA is measured with the component mounted on a low effective thermal conductivity test board in free air. See Tech Brief TB379 for details.
