ISO78xx Triple/Quad Digital Isolator Evaluation Module
This user’s guide describes the ISO78xx Triple/Quad Digital Isolator Evaluation Module (EVM). This EVM
allows designers to evaluate device performance for fast development and analysis of isolated systems.
The EVM supports evaluation of any of the TI triple- or quad-channel digital isolators in a 16DW package.
CAUTION
This evaluation module is made available for isolator parameter performance
evaluation only and is not intended for isolation voltage testing. To prevent
damage to the EVM, any voltage applied as a supply or digital input/output
must be maintained within the 0 V to 5.5 V recommended operating range.
