Description
MAX1487ESA Low Power Half-Duplex RS485 RS422 Transceiver
The MAX1487 are low-power transceivers for RS-485 and RS422 communication. Each part contains one driver and one receiver. The driver slew rates of the MAX481, MAX485, MAX490, MAX491, and MAX1487 are not limited, allowing them to transmit up to 2.5Mbps. These transceivers draw between 120µA and 500µA of supply current when unloaded or fully loaded with disabled drivers. it 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 MAX1487 feature quarter-unit-load receiver input impedance, allowing up to 128 MAX1487 transceivers on the bus. MAX1487 are designed for half-duplex applications.
