MAX3488ESA+

MAX3488ESA+ is a full duplex, low-power transceiver for RS-485 and RS-422 communication. It contains one driver and one receiver. This device 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. 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. It is used in applications such as low-power RS-485/RS-422 transceivers, telecommunications, transceivers for EMI-sensitive applications, industrial-control local area networks.
