Note 1. All currents into device pins are shown as positive, out of device pins are negative. All voltages
referenced to ground unless otherwise noted.
Note 2. Differential input threshold voltage and guaranteed output levels are done simultaneously
for worst case.
Note 3. Refer to EIA−422/3 for exact conditions. Input balance and guaranteed output levels are
done simultaneously for worst case.
Note 4. Only one output at a time should be shorted.
