CC

NOTE 3: The algebraic convention, where the more positive (less negative) limits 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 maintain the total power dissipation below absolute maximum ratings.
NOTE 5: Test conditions are those specified by EIA-232-E and as listed above.
