(4) Not more than one output should be shorted at a time. For testing I_OS, the use of high speed test apparatus and/or sample-and-hold

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 above normal and thereby cause invalid readings in other parameter tests. In

any sequence of parameter test, I_OStests should be performed last.
