Evaluation Module
ABSTRACT
This user's guide describes the evaluation module (EVM) for TI’s ISO1642, ISO1643, and ISO1644 isolated
I
2
C transceivers with general purpose input/output (GPIO) channels. This EVM helps designers evaluate
performance of these isolated devices in their 16-pinDW packages for quick development and analysis of data
transmission systems.
