(1) The DS92LV040A functions within datasheet specification when a resistive load is applied to the driver outputs.
(2) All currents into device pins are positive; all currents out of device pins are negative. All voltages are referenced to ground unless

fail-safe terminated test performed with 27Ω connected between RI+ and RI− inputs. No external voltage is applied.
(6) Propagation delays, transition times, and receiver threshold are ensured by design and characterization.
