3 Description

The

ISO782xLL

family

of

devices

is

a

high-

performance, isolated dual-LVDS buffer with 8000-

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

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.
