*Pb-free PDIPs can be used for through hole wave solder
processing only. They are not intended for use in Reflow solder
processing applications.
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 used to fabricate these devices, connecting any terminal to a voltage greater than V DD
or less then V SS 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 first.
2. θ JA is measured with the component mounted on a low effective thermal conductivity test board in free air. See Tech Brief 379 for details.
