All typicals are given for V CC = 5V and TA = 25°C. VCC and VEE as listed in operating conditions. (2) All currents into device pins are positive; all currents out of device pins are negative. All voltages are referenced to ground unless otherwise specified. (3) Only one output at a time should be shorted. (4) Symbols and definitions correspond to EIA RS-422 and/or RS-423 where applicable.
