Introduction
This user’s guide describes EVM operation with respect to the ISOW784x quad-channel digital isolators.
However, the EVM may be reconfigured for evaluation of any of TI’s triple- or quad-channel digital
isolators in a 16DW or 16DWE package. This guide also describes the available channel configurations
within the ISOW784x family, the EVM schematic, and typical laboratory setup. An efficiency plot and
typical input and output waveforms are also provided.

Overview
The ISOW784x is a family of high-performance, quad-channel reinforced digital isolators with an
integrated high-efficiency power converter. The integrated DC-DC converter provides up to 650 mW of
isolated power at high efficiency and can be configured for various input and output voltage configurations.
Therefore these devices eliminate the need for a separate isolated power supply in space-constrained
isolated designs. The ISOW784x family of devices provide high electromagnetic immunity and low
emissions while isolating CMOS or LVCMOS digital I/Os. The signal-isolation channel has a logic input
and output buffer separated by a silicon dioxide (SiO2) insulation barrier, whereas, power isolation uses
on-chip transformers separated by thin film polymer as insulating material. Various configurations of
forward and reverse channels are available. If the input signal is lost, the default output is high for the
ISOW784x devices and low for the devices with the F suffix. These devices help prevent noise currents on
a data bus or other circuits from entering the local ground and interfering with or damaging sensitive
circuitry. Through innovative chip design and layout techniques, electromagnetic compatibility of the
ISOW784x family of devices has been significantly enhanced to ease system-level ESD, EFT, surge and
emissions compliance. The high-efficiency of the power converter allows operation at a higher ambient
temperature.
