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.
3. These are maximum I
OL
values per output, for 8 outputs turned on simultaneously. Total maximum I
OL
(all outputs) is 512mA for commercial and
384mA for military. Derate I
OL
for number of outputs exceeding 8 turned on simultaneously.
4. The test limit for this parameter is
±
5
μ
A at T
A
= –55
°
C.
5. This parameter is guaranteed but not tested.
