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, connecting any terminal to voltages greater than V
DD
or less than V
SS
may
cause destructive device latchup. For this reason, it is recommended that no inputs from external sources not operating on the same
power supply be applied to the device before its supply is established, and that in multiple supply systems, the supply to the ICM7211
and ICM7212 be turned on first.
2. θ
JA
is measured with the component mounted on an evaluation PC board in free air.
