3.3V HIGH SPEED RS-485/RS-422 TRANSCEIVERS WITH 1/8th UNIT LOAD
NOTE:
1.
Change in Magnitude of Differential Output Voltage and Change in Magnitude of Common Mode Output Voltage
are the changes in output voltage when DI input changes state.
2.
Except devices which do not have DE or RE inputs.
3.
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 not enter shutdown. If the enable inputs
are held in this state for at least 600ns the device is assured to be in shutdown. Note that the receiver and driver
enable times increase during shutdown.
4.
Guaranteed by design and bench characterization.
