The algebraic convention, in which the less positive (more negative) limit is designated as minimum, is used in this data sheet for threshold voltage
levels only.
NOTES:
3. Refer to ANSI Standard RS-485 for exact conditions.
4. The duration of the short circuit should not cause the maximum package power dissipation to be exceeded.
