MAX3483, MAX3485, MAX3486, MAX3488, MAX3490以及MAX3491是用于RS-485与RS-422通信的3.3V，低功耗收发器，每个器件中都具有一个驱动器和一个接收器。MAX3483和MAX3488具有限摆率驱动器，可以减小EMI，并降低由不恰当的终端匹配电缆引起的反射，实现最高250kbps的无差错数据传输。MAX3486的驱动器摆率部分受限，可以实现最高2.5Mbps的传输速率。MAX3485,MAX3490和MAX3491则可以实现最高10Mbps的传输速率。
驱动器具有短路电流限制，并可以通过热关断电路将驱动器输出置为高阻状态，防止过度的功率损耗。接收器输入具有失效保护特性，当输入开路时，可以确保逻辑高电平输出。
使用MAX3488, MAX3490和MAX3491可以实现全双工通信，而MAX3483, MAX3485与MAX3486则为半双工应用设计。

The MAX3483, MAX3485, MAX3486, MAX3488, MAX3490, and MAX3491 are 3.3V, low-power transceivers for RS-485 and RS-422 communication. Each part contains one driver and one receiver. The MAX3483 and MAX3488 feature slew-rate-limited drivers that minimize EMI and reduce reflections caused by improperly terminated cables, allowing error-free data transmission at data rates up to 250kbps. The partially slew-rate-limited MAX3486 transmits up to 2.5Mbps. The MAX3485, MAX3490, and MAX3491 transmit at up to 10Mbps.
Drivers ar short-circuit current limited and are protected 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 fullduplex communication, while the MAX3483, MAX3485, and MAX3486 are designed for half-duplex communication.
