General Description

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 ±15kV using the Human 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.

The 20Mbps baud rate transmitters feature low-static

for battery-powered and power-conscious applications.

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–

MAX3033E feature hot-swap capability that eliminates

false transitions on the data cable during power-up or

hot insertion.

The MAX3030E–MAX3033E are low-power, ESD-pro-

tected, pin-compatible upgrades to the industry-stan-

dard 26LS31 and SN75174. They are available in

space-saving 16-pin TSSOP and SO packages.
