For conditio shown as MIN or MAX, use the appropriate value specified under recommended operating conditio for the applicable type.. All typical values are at V CC = V, T amb = C.. 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 well above normal and thereby cause invalid readings in other parameter tests. In any sequence of parameter tests, I OS tests should be performed last.

For example, changing the specified pull up resistor value from 00Ω to 0Ω will improve the up to 0% with only a slight increase in the. However, if the value of the pull up resistor is changed, the user must make certain that the total I OL current through the resistor and the total I IL s of the receivers does not exceed the I OL maximum specification.
