NOTES:
5. The algebraic convention, where the more positive (less negative) limit is designated as maximum, is used in this data sheet for logic
levels only (e.g., if −10 V is maximum, the typical value is a more negative voltage).
6. Output short-circuit conditions must maintain the total power dissipation below absolute maximum ratings.
7. Test conditions are those specified by TIA/EIA-232-F and as listed above.
