Long traces bounded by a V

and/or GND planes can add
substantial parasitic capacitance. Parasitic capacitances
on the receiver/driver outputs can also unduly slow down
both the propagation delay and the rise/fall times.

The receiver inputs are high bandwidth and high imped-
ance. If they are left floating, any capacitive coupling from
any other signal can cause a glitch at the receiver output.
Thus, if the receiver is not being used, it is advisable to
always ground at least one of the two receiver input pins.
