Industrial automation equipment Grid infrastructure Solar inverter Motor drivers HVAC General Description The CA-IS2082B device is a galvanically-isolated RS-485/RS422 transceiver that has superior isolation and RS-485 performance to meet the critical needs of the industrial applications. This device has the logic input and output Copyright © 2020, Chipanalog Incorporated Shanghai Chipanalog Microelectronics Co., Ltd. buffers separated by a silicon oxide (SiO2) insulation barrier that provides galvanic isolation, features up to 3000VRMS (60s) of galvanic isolation and ±100kV/μs typical CMTI. Isolation improves communication by breaking ground loops and reduces noise where there are large differences in ground potential between different ports. The CA-IS2082B is designed for high-speed (up to 5Mbps) multidrop operation with high ESD protection of up to ±8kV HBM and ±12kV IEC 61000-4-2 Contact Discharge ESD protection on bus I/O pins. The receiver is 1/8-unit load, allowing up to 256 transceivers (loads) on a common bus. Maintaining multidrop operation and increasing the maximum data rate offer a more robust system design for reliable data transmission in the harsh environments. This device provides half-duplex transceiver, the driver and receiver enable pins let any node at any given moment be configured in either transmit or receive mode which decreases cable requirements. The CA-IS2082B is available in 16-pin SSOP package which is the industry standard isolated RS-485/RS-422 package, and operates over -40°C to +125°C temperature range.
