For conditions shown as MIN or MAX, use the appropriate value specified under recommended operating conditions.
All typical values are at VCC = 5 V, TA = 25

C.
§The minimum VOD2 with a 100-
load is either 1/2 VOD1 or 2 V, whichever is greater.
| VOD | and
| VOC | are the changes in magnitude of VOD and VOC, respectively, that occur when the input is changed from a high level to
a low level.
#Not more than one output should be shorted at a time, and duration of the short circuit should not exceed one second.
