MAX483EPA+

MAX483EPA+ is a half-duplex, low-power transceiver for RS-485 and RS422 communication. 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 an open circuit. It is used in applications such as low-power RS-485 transceivers, low-power RS-422 transceivers, level translators, transceivers for EMI-sensitive applications, and industrial-control local area networks.
