How to Design with Capacitive Digital Isolators 6

Figure 6: Connect the bypass capacitor directly to the VCC terminal

Multiple via holes are used to connect bypass capacitors and other protective devices (such as transient voltage suppressors and Zener diodes), thereby minimizing the via inductance of the ground connection.

Summary

Although there is a lot of information about PCB design, this article mainly provides some suggestions related to the design of digital isolator circuit boards. Following these recommendations will help to complete a circuit board design that meets EMC standards in the shortest possible time.  diode
