The ADuM220N/ADuM221N/ADuM225N/ADuM226N isolators operate on either side of a supply voltage ranging from 1.8V to 5V. The capability to operate on either side of the supply voltage enables voltage translation functionality across the isolation barrier and compatibility with lower voltage systems.
Based on iCoupler® technology, the ADuM220N/ADuM221N/ADuM225N/ADuM226N isolators ensure DC correctness in the absence of input logic transitions. Additionally, the isolators feature two different fail-safe options. The fail-safe options allow the outputs to transition to a predetermined state when the input power supply is not applied or the inputs are disabled.
