Product Summary
The MAX3491ESD is a 3.3V, low-power transceiver for RS-485 and RS-422 communication. The MAX3491ESD contains one driver and one receiver. TheMAX3491ESD transmits at up to 10Mbps. The applications of the MAX3491ESD include Low-Power RS-485/RS-422 Transceivers, Telecommunications, Transceivers for EMI-Sensitive Applications and Industrial-Control Local Area Networks. The MAX3491ESD feature fullduplex communication. 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 of the MAX3491ESD has a fail-safe feature that guarantees a logic-high output if both inputs are open circuit.
