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 ICM7211AM be turned on first.
2. θ
JA
is measured with the component mounted on an evaluation PC board in free air.

are considered to be normal operating input logic levels. Actual input low and high levels are specified
under Operating Characteristics. For lowest power consumption, input signals should swing over the full supply.
