Note 3:
The transceivers are put into shutdown by bringing
RE
high and DE low. If the inputs are in this state for less than 80ns, the
devices are guaranteed not to enter shutdown. If the inputs are in this state for at least 300ns, the devices are guaranteed
to have entered shutdown. See Low-Power Shutdown Mode section.
