†
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.

= 25°C and V
CC
= 5 V, with the exception of I

at 7 V.
§
Only one output should be shorted at a time, and duration of the short circuit should not exceed one second.
