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. TA = 25oC.
2. Due to the SCR structure inherent in the CMOS process, connecting any terminal at voltages greater than VDD or less than VSS 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 ICM7170 be turned on first.
3. θJA is measured with the component mounted on an evaluation PC board in free air.
DC Electrical Specifications TA = -40oC to 85oC, VDD +5V ±10%, VBACKUP VDD, VSS = 0V Unless Otherwise Specified
All IDD specifications include all input and output leakages (ICM7170 and ICM7170A)
