The MAX489CSD from Maxim Integrated is a low-power transceiver suitable for RS-485 and RS-422 communication applications. Each unit integrates one driver and one receiver, operating from a single 5V supply.
This transceiver supports data rates up to 2.5Mbps, with reduced slew-rate drivers available for applications requiring minimized EMI and reduced reflections, allowing for error-free transmission up to 250kbps. It draws minimal supply current, between 120µA and 500µA when unloaded or fully loaded with disabled drivers. For power-sensitive designs, certain variants offer a low-current shutdown mode consuming only 0.1µA.
Drivers are protected against short-circuit conditions and excessive power dissipation through thermal shutdown circuitry. The receiver input includes a fail-safe feature, ensuring a logic-high output if the input becomes open-circuited. The MAX489CSD is designed for half-duplex communication.
Applications include low-power RS-485 and RS-422 transceivers, level translators, transceivers for EMI-sensitive applications, and industrial-control local area networks. The device is available in a 14-SOIC package and is designed for surface mount installation.
