ANALOG DEVICES MAX3087EESA+

The MAX3087EESA+ is a ±15KVESD protected, fail-safe, high speed RS485/RS422 transceiver in 8 pin NSOIC package. It contains one driver and one receiver. The device features fail-safe circuitry which has a logic high receiver output when the receiver inputs are open or shorted. This means that the receiver output will be logic high if all transmitters on a terminated bus are disabled (high impedance). MAX3087EESA+ driver slew rate is not limited, making transmit speeds up to 10Mbps. The transmitter output and receiver input is protected by ±15KV using human body model with enhanced ESD protection. This transceiver typically draws 375µA of supply current when unloaded or when fully loaded with the drivers disabled. It has a 1/8 unit load receiver input impedance that allows up to 256 transceivers on the bus.
