The MAX3485ESA+T from Maxim Integrated is an RS-422/RS-485 Interface IC providing 3.3V 10Mbps logic-level signaling for half-duplex communication over asynchronous serial buses and low-cost twisted-pair cables. It is comprised of a low-power CMOS line transceiver with cable-length compensation that is specifically designed for control and data communication on multipoint buses. The device includes a pair of RS-422/RS-485 line receivers, one RS-422/RS-485 line driver, and a versatile set of control pins. It supports high-resolution data transmissions up to 10Mbps, and it can be configured for either half-duplex RS-485 communications in 2-wire, 4-wire, or 5-wire (or signal ground) wiring configurations. The device is available in an 8-pin SOIC package.
