reliability and result in failures not covered by warranty.
NOTES:
5. Due to the SCR structure inherent in the CM0S process used to fabricate these devices, connecting any terminal to a voltage greater than V
DD
or less
than V
SS
may cause destructive device latch-up. For this reason it is recommended that no inputs from 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 ICM7218 should be turned
on first.
