NOTES:
1. For conditions shown as Max. or Min., use appropriate value specified under Electrical Characteristics for the applicable device type.
2. Typical values are at V
CC
= 5.0V, +25
°
C ambient and maximum loading.
3. Not more than one output should be shorted at one time. Duration of the short circuit test should not exceed one second.
4. This parameter is guaranteed but not tested.
5. These are maximum I
OL
values per output, for 10 outputs turned on simultaneously. Total maximum I
OL
(all outputs) is 480mA for commercial and 320mA
for military. Derate I
OL
for number of outputs exceeding 10 turned on simultaneously.
