Note 2: “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. 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 specified.
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.
