Systems can have multiple digital voltages that are similar in value which need to be separated for optimal performance. For example, an incoming 3.3-V signal may need to communicate with an internally regulated 3.3-V device, and the two may vary separately from 3 V to 3.6 V. In this case, true isolation is not required, however separation of the voltage nodes will prevent issues from the voltage mismatch.
