tFor conditions shown as MIN or MAX, use appropriate value specified under recommended operating conditions.
+AII typical values are at Vee = 5 V, TA = 25°C.
§The output conditions have been chosen to produce a current that closely approximates one half of the true short-circuit output current, lOS.
