ELECTRICAL SPECIFICATIONS

13.1 ABSOLUTE MAXIMUM RATINGS1

NOTES

Stresses greater than those listed under ‘Absolute maximum ratings’ may cause permanent damage to the device. This

is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the

operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended pe-

riods may affect reliability.

For 3V tolerant pins VDD = 3.3V

± 0.3V, for 5V tolerant pins (PCI, Video Port and Serial interfaces) VDD = 5V ± 0.5V
