NOTE 3: The algebraic convention, where the more positive (less negative) limitis designated as maximum, is used in this datasheet for logic levels only
(e.g. if -10V is a maximum, the typical value is a more negative voltage).
NOTE 4: Output short circuit conditions must mantain the total power dissipation below absolute maximum ratings.
NOTE 5: Testconditions are those specified by EIA-232-E and as listed above.
