® ISO 485 ISO485 Isolated RS-485 DIFFERENTIAL BUS TRANSCEIVER FEATURES q RS-485 AND RS-422 COMPATIBLE q 100% TESTED FOR HIGH-VOLTAGE BREAKDOWN q q q q RATED 1500Vrms SINGLE-WIDE 24-PIN PLASTIC DIP EASY TO USE LOW POWER: 180mW typ at 5Mbit/s DESCRIPTION The ISO485 differential, isolated bus transceiver uses Burr-Brown’s capacitively coupled isolation technology to provide high-speed, low cost bus isolation. The ISO485 is designed for bi-directional data communication on multipoint bus transmission lines and meets EIA Standard RS-485 as well as EIA Standard RS-422A requirements. The ISO485 uses high voltage 0.4pF capacitors instead of the LED and photodetector which are used in equivalent optocoupler solutions.
