DC ELECTRICAL CHARACTERISTICS OVER OPERATING RANGE
FollowingConditionsApplyUnlessOtherwiseSpecified:
Industrial: TA = –40°C to +85°C, VCC = 5.0V ±5%; Military: TA = –55°C to +125°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 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.
