NOTES:

1. For conditions shown as MIN or MAX, use the appropriate value specified under the 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. In any
