t For conditions shown as MIN or MAX, use appropriate value specified under recommended operating conditions.
i All typical values are at Vee = 5, V, T A = 15°e.
§ The output conditions have been chosen to produce a current that closely approximates one half of the true short-circuit output current, lOS.
