  TJ485 is low-power transceiver for RS-485 and RS-422 communication. The IC contains one driver and one receiver. The driver slew rates of the TJ485 is not limited, allowing them to transmit up to 2.5 Mbps. These transceivers draw between 120 uA and 500 uA of supply current when unloaded or fully loaded with disables 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 TJ485 is designed for half-duplex applications.
