The MAX490ESA is a low-power transceiver designed for RS-485 and RS-422 communication applications. It features a single driver and receiver, capable of transmitting data at speeds up to 2.5Mbps. This device operates from a single 5V supply and draws minimal current, between 120µA and 500µA when unloaded or fully loaded with disabled drivers.
The transceiver includes built-in protection features such as short-circuit current limiting and thermal shutdown circuitry to prevent excessive power dissipation. The receiver input has a fail-safe feature that ensures a logic-high output if the input is open circuit. The MAX490ESA is designed for half-duplex communication and is housed in an 8-SOIC package suitable for surface mounting.
Applications for the MAX490ESA include low-power RS-485 and RS-422 transceivers, level translators, transceivers for EMI-sensitive applications, and industrial-control local area networks.
