6. Errata and Design Migration Guidelines
The following errata apply to Revision A devices only. See "8.Ordering Guide" on page 25 for more details. No
errata exist for Revision B devices.
6.1. Power Supply Bypass Capacitors (Revision A and Revision B)
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, > 1 µF capacitors are required on both power supply pins
(VDD1, VDD2) of the isolator device.
6.1.1. Resolution
This issue has been corrected with Revision B of the device. Refer to “8. Ordering Guide” for current ordering
information.
