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 speciï¬cation is not implied.
NOTES:
1. Due to the SCR structure inherent in the CMOS process used to fabricate these devices, connecting any terminal to a voltage greater
than VDD or less then VSS may cause destructive device latchup. For this reason, it is recommended that no inputs row 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 ICM7228 should be turned on ï¬rst.
2. θJA is measured with the component mounted on an evaluation PC board in free air.
Electrical Speciï¬cations VDD = +5.0V ±10%, VSS = 0V, Unless Otherwise Speciï¬ed
