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 DS16F95 and across the 0˚C to +70˚C range for the
DS36F95. All typicals are given for V
Note 4: All currents into the device pins are positive; all currents out of the device pins are negative. All voltages are referenced to ground unless otherwise specified.
Note 5:

Note 7: The algebraic convention, where the less positive (more negative) limit is designated minimum, is used in this data sheet for common mode input voltage
and threshold voltage levels only.
Note 8: Hysteresis is the difference between the positive-going input threshold voltage, V
Note 9: Refer to TIA/EIA-485 Standard for exact conditions.
Note 10: Only one output at a time should be shorted.
