General Description
The MAX3483,MAX3485,MAX3486,MAX3488,
MAX3490,and MAX3491 are 3.3V,low-power trans-
ceivers for RS-485 and RS-422 communication.Each
part contains one driver and one receiver.The
MAX3483 and MAX3488 feature slew-rate-limited dri-
vers that minimize EMI and reduce reflections caused
by improperly terminated cables,allowing error-free
data transmission at data rates up to 250kbps.The par-
tially slew-rate-limited MAX3486 transmits up to
2.5Mbps.The MAX3485, MAX3490, and MAX3491
transmit at up to 10Mbps.
Drivers are short-circuit current limited and are protect-
ed against excessive power dissipation by thermal
shutdown circuitry that places the driver outputs into a
high-impedance state.The receiver input has a fail-safe
feature that guarantees a logic-high output if both
inputs are open circuit.
The MAX3488,MAX3490,and MAX3491 feature full-
duplex communication,while the MAX3483,MAX3485,
and MAX3486 are designed for half-duplex communi-
cation.
