Product Summary

The MAX3082CSA is a high-speed transceiver for RS-485/RS-422 communication contains one driver andone receiver. The device features fail-safe circuitry, which guarantees a logic-high receiver output while thereceiver inputs are open or shorted. It means that the receiver output will be a logic high if all transmitterson a terminated bus are disabled (high impedance). The MAX3082CSA features reducedslew-rate drivers that minimize EMI and reduce reflec-tions caused by improperly terminated cables, allowing error-free data transmission up to 115kbps. The transceiver typically draws 375μA of supplycurrent when unloaded, or when fully loaded with thedrivers disabled. The applications of the include RS-422/RS-485 Communications, Level Translators, Transceivers for EMI-Sensitive Applications, Industrial-Control Local Area Networks.
