MAX1480BCPI+, Интерфейс RS-485/RS-422 изолированный …The MAX1480BCPI+ is a complete electrically isolated RS-485/RS-422 data-communications Interface Solution in a hybrid microcircuit. A single +5V supply on the logic side powers both sides of the interface. The MAX1480B feature reduced-slew-rate drivers that minimize EMI and reduce reflections caused by improperly terminated cables, allowing error-free data transmission at data rates up to 250kbps. The MAX1480B is designed for half-duplex communication. Drivers are short-circuit current limited and 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 known output (active-low RO low for the MAX1480B, RO high for the MAX1490B) if the input is open circuit.
