NOTES:

1. 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 approximates one half of the true short-circuit output current, IOS.
