(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.

Refer to EIA Standards RS-485 for exact conditions.

(6)

Only one output at a time should be shorted.
