Note 2:
“Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. They are not meant to imply that the devices
should be operated at these limits. The table of “Electrical Characteristics” provides conditions for actual device operation.
Note 3:
All currents into device pins are shown as positive, out of device pins are negative. All voltages referenced to ground unless otherwise noted.
Note 4:
Only one output at a time should be shorted.
Note 5:
Refer to EIA RS-422/3 for exact conditions.
