DC ELECTRICAL CHARACTERISTICS OVER OPERATING RANGE
Following Conditions Apply Unless Otherwise Specified: VLC = 0.2V; VHC = VCC - 0.2V
Commercial: TA = 0°C to +70°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 and maximum loading.
3. Not more than one output should be tested at one time. Duration of the test should not exceed one second.
4. This parameter is guaranteed but not ttested.
