(1) Unless otherwise specified, min/max limits apply across the −55°C to +125°C temperature range for the DS1691A and across the 0°C to
+70°C range for the DS3691. All typicals are given for V _CC = 5V and T_A = 25°C. V_CC and V_EE 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.
(5) At −55°C, the output voltage is +3.9V minimum and −3.9V minimum.
