... Power Supply Bypass Capacitors (Revision C Only) When using the ISOpro isolators with power supplies > 4.5 V, sufficient VDD bypass capacitors must be present on both the VDD1 and VDD2 pins to ensure the VDD rise time is less than 0.5 V/µs (which is > 9 µs for a > 4.5 V supply). Although rise time is power supply dependent, > ...
