Ordering Information continued at end of data sheet.
General DescriptionThe MAX3080E–MAX3089E are ±15kV electrostatic dis-
charge (ESD)-protected, high-speed transceivers for RS-
485/RS-422 communication that contain one driver and
one receiver. These devices feature fail-safe circuitry,
which guarantees a logic-high receiver output when the
receiver inputs are open or shorted. This means that the
receiver output will be a logic high if all transmitters on a
terminated bus are disabled (high impedance). The
MAX3080E/MAX3081E/MAX3082E feature reduced
slew-rate drivers that minimize EMI and reduce reflec-
tions caused by improperly terminated cables, allowing
error-free data transmission up to 115kbps. The
MAX3083E/MAX3084E/MAX3085E offer higher driver
output slew-rate limits, allowing transmit speeds up to
500kbps. The MAX3086E/MAX3087E/ MAX3088Es’ dri-
ver slew rates are not limited, making transmit speeds
up to 10Mbps possible. The MAX3089E’s slew rate is
selectable between 115kbps, 500kbps, and 10Mbps by
driving a selector pin with a single three-state driver. All
devices feature enhanced ESD protection. All transmitter
outputs and receiver inputs are protected to ±15kV
using the Human Body Model.
These transceivers typically draw 375µA of supply
current when unloaded, or when fully loaded with the dri-
vers disabled.
All devices have a 1/8-unit-load receiver input impedance
that allows up to 256 transceivers on the bus. The
MAX3082E/MAX3085E/MAX3088E are intended for half-
duplex communications, while the MAX3080E/MAX3081E/
MAX3083E/MAX3084E/MAX3086E/MAX3087E are
intendedfor full-duplex communications. The MAX3089E
is selectable between half-duplex and full-duplex opera-
tion. It also features independently programmable
receiver and transmitter output phase via separate pins.

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.

Note 2:∆VODand ∆VOCare the changes in VODand VOC, respectively, when the DI input changes state.
Note 3:The SRL pin is internally biased to VCC / 2 by a 100kΩ/100kΩresistor-divider. It is guaranteed to be VCC / 2 if left
unconnected.
Note 4:Maximum current level applies to peak current just prior to foldback-current limiting; minimum current level applies during
