DC ELECTRICAL CHARACTERISTICS OVER OPERATING RANGE (B PORT, 5V)

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.

5. Duration of the condition cannot exceed one second.
