NOTES:

1. For conditions shown as MIN or MAX, use the appropriate value specified under recommended operating conditions for the applicable type.

techniques are preferable in order to minimize internal heating and more accurately reflect operational values. Otherwise, prolonged

shorting of a HIGH output may raise the chip temperature well above normal and thereby cause invalid readings in other parameter tests.
