Notes: 1. An operation exceeding the above absolute maximum ratings may cause a malfunction or
permanent damage of devices. The device reliability may drop excessively even if the devices
temporarily operate normally.
2. Electrical potential to peripheral systems:
The S1F76540 common power supply has the highest potential (V
DD). The electrical poten-
tial given by this specification is based on V
DD = 0 V. Take care to avoid a potential problem
during connection to a peripheral system.
