For conditions shown as MIN or MAX, use the appropriate value specified under recommended operating conditions for the applicable type. 2. All typical values are at VCC = 5V, Tamb = 25°C. 3. The output conditions have been chosen to produce a current that closely approximate one half of the true short-circuit output current, IOS .
