Product Summary

The MAX3485ECSA+T is a 3.3V, low-power transceiver for RS-485 and RS-422 communication. Each part contains one driver and one receiver. The MAX3485ECSA+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 MAX3485ECSA+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 MAX3485ECSA+T features full-duplex communication, while the MAX3485ECSA+T is designed for half-duplex communication.
