General Desc ription
The MAX3080–MAX3089 high-speed transceivers for
RS-485/RS-422 communication 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 MAX3080/MAX3081/MAX3082 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
MAX3083/MAX3084/MAX3085 offer higher driver out-
put slew-rate limits, allowing transmit speeds up to
500kbps. The MAX3086/MAX3087/MAX3088’s driver
slew rates are not limited, making transmit speeds up
to 10Mbps possible. The MAX3089’s slew rate is
selectable between 115kbps, 500kbps, and 10Mbps
by driving a selector pin with a single three-state
driver.
These transceivers typically draw 375μA of supply
current when unloaded, or when fully loaded with the
drivers disabled.
All devices have a 1/8-unit-load receiver input imped-
ance that allows up to 256 transceivers on the bus. The
MAX3082/MAX3085/MAX3088 are intended for half-
duplex communications, while the MAX3080/MAX3081/
MAX3083/MAX3084/MAX3086/MAX3087 are intended
for full-duplex communications. The MAX3089 is selec-
table between half-duplex and full-duplex operation. It
also features independently programmable receiver
and transmitter output phase via separate pins.
