MAX3087ESA+

The MAX3087ESA+ is a fail-safe, high speed (10Mbps), RS485/RS422 transceiver in 8 pin NSOIC package. The fail-safe circuitry in this device features a logic high receiver output when receiver inputs are open or shorted, it means that the receiver output will be a logic high if all transmitters on a terminated bus are disabled (high impedance). The driver slew rates is not limited, making transmit speed up to 10Mbps. It has a 1/8 unit load receiver input impedance that allows up to 256 transceivers on the bus.
