Notes:
1. Functional and tested operating conditions are given in Table 2 . Absolute maximum ratings are stress
ratings only, and functional operation at the maximums is not guaranteed. Stresses beyond those
listed may affect device reliability or cause permanent damage to the device.
2. Caution: Vin must not exceed OVdd by more than 0.3V at any time, including during power-on reset.
3. Caution: OVdd must not exceed Vdd/AVdd by more than 1.2V at any time, including during power-on
reset.
4. Caution: Vdd/AVdd must not exceed OVdd by more than 0.4V at any time, including during power-on
reset.
Table 2 provides th e recom m en ded operatin g con dition s for th e PPC740 an d PPC750.
