DC ELECTRICAL CHARACTERISTICS OVER OPERATING RANGE

FollowingConditionsApplyUnlessOtherwiseSpecified:

Industrial: TA = –40°C to +85°C, VCC = 5.0V ±10%

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 VCC = 5.0V, +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. Duration of the condition can not exceed one second.

5. The test limit for this parameter is ±5

μA at TA = -55°C.
