Product Summary

The MAX1487ESA+ is a low-power transceivers for RS-485 and RS-422 communication. Each part contains one driver and one receiver. The driver slew rates of the MAX1487ESA+ is not limited, allowing them to transmit up to 2.5Mbps. These transceivers draw between 120mA and 500mA of supply current when unloaded or fully loaded with disabled drivers. All parts operate from a single 5V supply. 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 the input is open circuit. The MAX1487ESA+ feature quarter-unit-load receiver input impedance, allowing up to 128 MAX487/MAX1487 transceivers on the bus.
