UNISONIC TECHNOLOGIES CO., LTD UTRS3085 Preliminary FAIL-SAFE, 2.5MBPS, RS-485 / RS-422 TRANSCEIVERS WITH ±12KV ESD-PROTECTED  DESCRIPTION The UTC UTRS3085 high-speed transceivers for RS-485/RS-422 communication contain one driver and one receiver. The device features 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 logic high if all transmitters on a terminated bus are disabled (high impedance). The UTC UTRS3085 offer higher driver output slew-rate limits, allowing transmission up to 2.5Mbps. The transceiver typically draws 375µA of supply current when unloaded or when fully loaded with the drivers disabled.
