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 V
= 5V, T
= 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, I
OS
.
