ANALOG DEVICES MAX3082CSA+

The MAX3082CSA+ is a fail-safe, high-speed (10Mbps), slew-rate-limited Transceiver for RS-485/RS-422 communication contain one driver and one receiver. This device feature fail-safe circuitry, which guarantees a logic-high receiver output when the receiver inputs are open or shorted. This means that the receiver output will be a logic high if all transmitters on a terminated bus are disabled (high impedance). The MAX3082 feature reduced slew-rate drivers that minimize EMI and reduce reflections caused by improperly terminated cables, allowing error-free data transmission up to 115kbps. This transceiver typically draw 375µA of supply current when unloaded or when fully loaded with the drivers disabled. All devices have a 1/8-unit-load receiver input impedance that allows up to 256 transceivers on the bus. The MAX3082 is intended for half-duplex communications.
