MAX13085

The MAX13085 is a half-duplex high speed transceiver for RS - 485 and RS422 communication. IC contains one driver and one receiver. The MAX13085 has a fail-safe circuit. It has a slew-rate-limited driver that reduces EMI and reflection due to improperly matched terminal cables, and achieves error-free data transmission of up to 2Mbps. Each driver output and receiver input is protected against ±15kV electrostatic discharge (HBM) (ESD) shocks. The MAX13085 receiver has 1/8 unit load input impedance, allows up to 256 devices can be attached to the bus. Mainly used in RS - 485/RS - 422 communication system.
