The ISO782xLL family of devices is a high-performance, isolated dual-LVDS buffer with 8000-VPK isolation voltage. This device 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 ISO7820LL device has two forward-direction channels. The ISO7821LL device has one forward and one reverse-direction channel.

Through innovative chip design and layout techniques, the electromagnetic compatibility of the ISO782xLL family of devices has been significantly enhanced to ease system-level ESD, EFT, surge, and emission compliance.

The ISO782xLL family of devices is available in 16-pin SOIC wide-body (DW) package and extra-wide body (DWW) packages.

For all available packages, see the orderable addendum at the end of the data sheet.
