† 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.
