twisted-pair balanced lines in accordance with TIA/EIA-
422-B and ITU-T V.11 standards. All transmitter outputs ±15k V ESD Protection on Tx Outputs
are protected to ±15k V using the Human Body Model.
Hot-Swap Functionality
The MAX3030E–MAX3033E are available with either a
2Mbps or 20Mbps guaranteed baud rate. The 2Mbps Guaranteed 20Mbps Data Rate (MAX3030E,
baud rate transmitters feature slew-rate-limiting to mini- MAX3032E) mize EMI and reduce reflections caused by improperly

current consumption (ICC < 100µA), making them ideal
for battery-powered and power-conscious applications. Packages
They have a maximum propagation delay of 16ns and a

part-to-part skew less than 5ns, making these devices
ideal for driving parallel data. The MAX3030E– +3.3V Operation
