Illustrative Applications
NVE offers a unique line of single-chip isolated RS-485, PROFIBUS, and CAN transceivers, but as illustrated in the circuits below, IL700-Series
Isolators can also be used as part of multi-chip designs with non-isolated transceivers:

Figure 2. Isolated CAN circuit.
CAN isolation is increasingly necessary to reduce EMI susceptibility, especially in high- speed applications and in hybrid and electrical vehicle
networks, where the 12 V battery has been replaced with one of several hundred volts. Operator and equipment safety becomes critical when a
high voltage source, such as the battery, needs to be connected to diagnosis systems during routine maintenance procedures. In the application
shown above, the microcontroller is isolated from the CAN transceiver by an IL712 or IL721, allowing higher speed and more reliable bus
operation by eliminating ground loops and reducing susceptibility to noise and EMI events. The best-in-class 10 ns typical IL712/IL721
propagation delay minimizes CAN loop delay and maximizes data rate over any given bus length. This simple circuit works with any CAN
transceiver with a TxD dominant timeout, which includes all of the current-generation transceivers.
