The ISO7821LLDWR 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 separated by silicon dioxide (SiO2) insulation barrier. The electromagnetic compatibility of the device has been significantly enhanced to ease system level ESD, EFT, surge and emission 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, GB4943.1-2011 CQC certification safety and regulatory approvals.
