Using optocouplers is a common, inexpensive method of signal isolation, but your application may be unable to tolerate optocouplers’ tendency to degrade with age and temperature. Targeting that problem, NVE has introduced the IsoLoop IL500 series of nonoptical digital isolators that operate as fast as 2 Mbps. The parts feature a patented, controllable refresh clock to ensure I/O synchronization within 9 microsec; some models in the series allow the use of an external synchronization clock. Maximum propagation delay is 25 nsec, and pulse-width distortion is 10 nsec....”
