MAX3485EESA+ Datasheet PDF - Maxim Integrated

The MAX3485EESA+ is a low-power slew-rate-limited True Transceiver for RS-485/RS-422 communications. Each device contains one driver and one receiver. The MAX3485EESA+ feature 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 12Mbps. All devices feature enhanced electrostatic discharge (ESD) protection. All transmitter outputs and receiver inputs are protected to ±15kV using IEC 1000-4-2 air-gap discharge, ±8kV using IEC 1000-4-2 contact discharge and ±15kV using the human body model. 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.
