Overview

ISO1644DWEVM is an evaluation module used to help designers evaluate the ISO1642, ISO1643, and ISO1644 devices' performance for quick development and analysis of data transmision systems using TI's ISO1642, ISO1643, and ISO1644 isolated I²C devices with general purpose input and output channels in 16-pin DW packages.

Features
  • Isolated, bidirectional, I²C-compatible communication with unidirectional GPIO channels
  • For evaluation of ISO1642, ISO1643, and ISO1644 devices in DW packages
  • Supply voltage and level translation Range: 3 V to 5.5 V on side 1 and 2.25 V to 5.5 V on side 2
  • Test points and headers for stand-alone evaluation or evaluation with larger systems
  • Isolation barrier Life >40 years
I2C isolators
