Note. 1. For voltage logic levels, the more positive (less negative) limit is designated as maximum, (e.g. if -10V is a
maximum, the typical value is a more negative voltage).
2: Output short circuit conditions must maintain the total power dissipation below absolute maximum ratings
and the sign is used to indicate direction.
3: Test conditions are those specified by TIA/EIA232-F and as listed above.
