MAX485ESA RS422/RS485 Interface IC

MAX485ESA RS422, RS485 Communication Interface IC is SO8 Package

MAX485 is a low power transceivers for RS485 and RS422 communication. MAX485 contains one driver and one receiver. The driver slew rates of the MAX485 are not limited, allowing it to transmit up to 2.5Mbps.

These transceivers draw between 120µA and 500µA of supply current when unloaded or fully loaded with disabled drivers. MAX485ESA RS422 RS485 IC operates 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.
