Product Summary

The MAX3485CSA+T is a 3.3V, low－power transceiver for RS－485 and RS－422 communication. Each part contains one driver and one receiver. The MAX3485CSA+T features 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 MAX3485CSA+T transmits at up to 10Mbps. Drivers are 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 MAX3485CSA+T features full－duplex communication, while the MAX3485CSA+T is designed for half－duplex communication.
