Introduction
This user’s guide describes EVM operation with respect to the ISO7762DBQ six-channel digital isolators.
However, the EVM may be reconfigured for evaluation of any of TI’s six-channel digital isolators in a 16pin SSOP (DBQ) package. This guide also describes the available channel configurations within the
ISO776x family, the EVM schematic, and typical laboratory setup. A typical input and output waveform is
also presented.

Overview
The ISO776x is TI’s new digital isolator family capable of galvanic isolations up to 4000 VPK. The devices
are certified to meet reinforced isolation requirements by VDE and CSA. These isolators provide high
electromagnetic immunity and low emissions at low power consumption, while isolating CMOS or
LVCMOS digital I/Os. The ISO776x digital isolators have logic input and output buffers separated by a
silicon oxide (SiO2) insulation barrier. Used with isolated power supplies, these devices block high
voltages, isolate grounds, and prevent noise currents on a data bus or other circuits from entering the
local ground and interfering with, or damaging sensitive circuitry.
