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 0C to +70C range for the DS96173/DS96175. All typicals are given for VCC = 5V and TA = 25C.
Note 4: All currents into the device pins are positive; all currents out of the device pins are negative. All voltages are reference to ground unless otherwise specified.
Note 5: The algebraic convention, when 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 6: Hysteresis is the difference between the positive-going input threshold voltage, VT+, and the negative going input threshold voltage, VT.
Note 7: Refer to EIA Standards RS-485 for exact conditions.
Note 8: Only one output at a time should be shorted.
