Note 1:
“Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. They are not meant to imply that the devices
should be operated at these limits. The table of “Electrical Characteristics” provides conditions for actual device operation.
Note 2:
All currents into device pins are positive; all currents out of device pins are negative.All voltages are referenced to ground unless otherwise specified except

1.0 ns (0%–100%). To ensure fastest propagation delay and
minimum skew, data input edge rates should be equal to or faster than 1ns/V; control signals equal to or faster than 3ns/V. In general, the faster the input edge rate,
the better the AC performance.
Note 7:
The DS92LV090A functions within datasheet specification when a resistive load is applied to the driver outputs.
Note 8:
Propagation delays are guaranteed by design and characterization.

failsafe terminated test performed with 27
connected between RI+ and RI inputs. No external voltage is applied.
Note 12:
Chip to Chip skew is the difference in differential propagation delay between any channels of any devices, either edge.
Note 13:
Channel to Channel skew is the difference in driver output or receiver output propagation delay between any channels within a device, common edge.
