Maxim MAX3483/MAX3485/MAX3486/MAX3488/MAX3490/MAX3491 Datasheet
The MAX3483 through MAX3491 are 3.3V, low-power transceivers designed for RS-485 and RS-422 communication applications. Each part contains one driver and one receiver, with options available for both half-duplex and full-duplex modes depending on the specific model number.
These devices feature slew-rate limited drivers to minimize EMI and reduce reflections caused by improperly terminated cables, ensuring error-free data transmission at rates up to 250kbps or higher. They include short-circuit current limiting and thermal shutdown circuitry for driver overload protection, as well as a fail-safe receiver input that guarantees a logic-high output if both inputs are open circuit.
