† 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-Ω 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.
