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 0˚C to +70˚C range for the DS96173/DS96175. All typicals are given for VCC = 5V and TA = 25˚C. 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 otherwisespecified. 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. www.national.com 2
