Product Summary
The Intersil ISL81486IUZ is a BiCMOS, 5V powered, single transceiver that meets both the RS-485 and RS-422 standards for balanced communication, and features the larger output voltage and higher data rate - up to 40Mbps - required by high speed PROFIBUS applications. Unlike competitive products, the ISL81486IUZ is specified for 10% tolerance supplies (4.5V to 5.5V) and delivers at least a 2.3V differential output voltage over this supply range. This translates into longer reach, or better data integrity, at the exceptional 40Mbps data rate. The ISL81486IUZ presents a 0.6 unit load to the RS-485 bus, which allows up to 50 transceivers on the network.
