CAUTION: Stresses above those listed in âAbsolute Maximum Ratingsâ 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. θJA is measured with the component mounted on a low effective thermal conductivity test board in free air. See Tech Brief TB379 for details.
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.
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)
