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.

ABSOLUTE MAXIMUM RATINGS
DC ELECTRICAL CHARACTERISTICS

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

(3V ≤VCC≤3.6V, TA= TMINto TMAX, unless otherwise noted. Typical values are at VCC= +3.3V and TA= +25°C.)
Note 1:
All currents into the device are positive; all currents out of the device are negative. All voltages are referenced to device
ground, unless otherwise noted.
Note 2:
∆VODand ∆VOCare the changes in VODand VOC, respectively, when DI changes state.
Note 3:
Only one output shorted at a time.
Note 4:
This input current is for the hot-swap enable (EN_, EN, EN) inputs and is present until the first transition only. After the first
transition, the input reverts to a standard high-impedance CMOS input with input current ILEAK.
