Opto Isolating Fast Signals

Fast opto isolators (like the ACSL6400, HCPL-263L, etc) have a max propagation delay specification of around 100nS. To pass say a UART signal through, it is easy to calculate the affect of the propagation delay on the signals.  Actually for a single direction signal like a UART the propagation delay isn't too much of an issue at all if it is reasonably constant for […]
