±15kV ESD-Protected, 3.3V Quad RS-422 Transmitters
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
current consumption (ICC< 100µA), making them ideal
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.
