(1) 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.
(2) Hysteresis is the difference between the positive-going input threshold voltage, V_T+, and the negative-going input threshold voltage, V_T−.
(3) Refer to TIA/EIA-485 Standard for exact conditions.
