The MAX485 is low-power transceiver 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. All parts operate from a single 5V supply. Drivers are short-circuited 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.
NOTE: Product Images are shown for illustrative purposes only and may differ from the actual product.
Embedded systems: Data transfer between microcontrollers and peripherals.
Building management systems: HVAC, lighting, and security control interfaces.
Energy metering: Communication between meters and data loggers.
