General Description
The 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
intended for 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.
