NOTES:

1. All currents into device pins are shown as positive, out of device pins are negative. All voltages referenced to ground unless otherwise noted.

2. See EIA specifications EIA–422–A for exact test conditions.

This device contains circuitry to protect the

inputs against damage due to high static volt-

ages or electric fields; however, it is advised that

normal precautions be taken to avoid applica-

tions of any voltage higher than the maximum

rated voltages to this high impedance circuit.

For proper operation it is recommended that

Vin and Vout be constrained to the range VSS ≤

(Vin or Vout) ≤ VDD. Reliability of operation is

enhanced if unused inputs are tied to and

appropriate logic voltage level (e.g., either VSS

or VDD).
