DC ELECTRICAL CHARACTERISTICS OVER OPERATING RANGE (A PORT, 3.3V)

FollowingConditionsApplyUnlessOtherwiseSpecified:

VCC1 = 5V ±10%, VCC2 = 2.7V to 3.6V, Industrial: TA = –40°C to +85°C

NOTES:

1. For conditions shown as Min. or Max., use appropriate value specified under Electrical Characteristics for the applicable device type.

2. Typical values are at VCC1 = 5V, VCC2 = 3.3V, +25°C ambient.

3. Not more than one output should be shorted at one time. Duration of the test should not exceed one second.

4. This parameter is guaranteed but not tested.
