They are not meant to imply that the devices should be operated at these limits. The tables of “Electrical Characteristics” provide conditions for actual device operation. Note 3: 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 TA = 25˚C. VCC and VEE as listed in operating conditions. Note 4: All currents into device pins are positive; all currents out of device pins are negative. All voltages are referenced to ground unless otherwise speci fied. Note 5: Only one output at a time should be shorted. Note 6: Symbols and definitions correspond to EIA RS-422 and/or RS-423 where applicable. Note 7: At −55˚C, the output voltage is +3.9V minimum and −3.9V minimum.
