(1) Unless otherwise specified Min/Max limits apply across the 0°C to +70°C range for the DS96173/DS96175. All typicals are given for V_CC
= 5V and T_A = 25°C.
(2) 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.
(3) 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.
(4) Hysteresis is the difference between the positive-going input threshold voltage, V_T+, and the negative going input threshold voltage, V_T−.
(5) Refer to EIA Standards RS-485 for exact conditions.
(6) Only one output at a time should be shorted.
