DC ELECTRICAL CHARACTERISTICS OVER OPERATING RANGE

FollowingConditionsApplyUnlessOtherwiseSpecified:

Industrial: TA = –40°C to +85°C, VCC = 5.0V ±5%

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 tested at one time. Duration of the test should not exceed one second.

4. The test limit for this parameter is ±5µA at TA = –55°C.
