All parameters, with the exception of off-state open-collector output current, are measured with the active pullup connected to the sink output.
For conditions shown as MIN or MAX, use the appropriate value specified under recommended operating conditions.
All typical values are at TA = 25

C and VCC = 5 V, with the exception of ICC at 7 V.
§Only one output should be shorted at a time, and duration of the short circuit should not exceed one second.
