Rꢀꢁ422 Transmitters
General Description
Features
The MAX3030E–MAX3033E family of quad RS-422
transmitters send digital data transmission signals over
twisted-pair balanced lines in accordance with TIA/EIA-
422-B and ITU-T V.11 standards. All transmitter outputs
are protected to 1ꢀ5V using the ꢁuman Body Model.
The MAX3030E–MAX3033E are available with either a
2Mbps or 20Mbps guaranteed baud rate. The 2Mbps
baud rate transmitters feature slew-rate-limiting to mini-
mize EMI and reduce reflections caused by improperly
terminated cables.

They have a maximum propagation delay of 16ns and a
part-to-part s5ew less than ꢀns, ma5ing these devices
ideal for driving parallel data. The MAX3030E–
MAX3033E feature hot-swap capability that eliminates
false transitions on the data cable during power-up or
hot insertion.
