Taejin RS485 Interface Module

The MAX3485 module is a low-power half-duplex transceiver that meets the specifications of RS-485 and RS-422. IC contains one driver and one receiver. The driver slew rates is not limited, allowing them to transmit up to 10Mbps. The transceiver draws 425µA of supply current when unloaded or fully loaded with disabled driver. All parts operate from a single 3.3V supply. Driver is short-circuit current limited and is 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.
