The ISO7821LLSDWR from Texas Instruments is a high performance, 8000VPK reinforced isolated dual-LVDS buffer in 16 pin SOIC package. It provides high electromagnetic immunity and low emissions at low power consumption while isolating the LVDS bus signal. Each isolation channel has an LVDS receive and transmit buffer. Timing performance for the device is optimized for use with communication systems that use DC-balanced data streams which is achieved through an internal distortion correction scheme. The electromagnetic compatibility of the IC has been significantly enhanced to ease system-level ESD, EFT, surge and emissions compliance. The 8000-VPK reinforced isolation per DIN V VDE V 0884-10 (VDE V 0884-10):2006-12, 5700-VRMS isolation for 1 minute per UL 1577, CSA component acceptance notice 5A, IEC60950-1 and IEC 60601-1 end equipment standards, TUV certification per EN 61010-1 and EN 60950-1, CQC certification safety and regulatory approvals.
