NOTES:

1. The transceivers are put into shutdown by bringing RE high and DE low simultaneously for at least 600ns. If the control inputs are in this state for less than 50ns, the device

is guaranteed to not enter shutdown. If the enable inputs are held in this state for at least 600ns, the device is ensured to be in shutdown. Note that the receiver and driver

enable times increase significantly when coming out of shutdown.

2. This spec is guaranteed by design and bench characterization.
