Abstract: Methods and apparatus are disclosed for communicating multiple logic states across a digital isolator. The digital isolator is a universal serial bus (USB) isolator in some embodiments. The digital isolator includes one or more single-bit data channels. Three or more logic states of information are transmitted across the single-bit data channel(s). The logic states are distinguished by a pulse sequence, and in particular a number of edges of the pulse sequence and a final value or final edge of the pulse sequence.
