Product Summary
The MAX3485EPA is a 3.3V, low-power transceiver for RS-485 and RS-422 communication. Each part contains one driver and one receiver. The MAX3485EPA 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. Applications include Low-Power RS-485/RS-422 Transceivers, Telecommunications, Transceivers for EMI-Sensitive Applications and Industrial-Control Local Area Networks.
