3. Errata and Design Migration Guidelines
When using the new ISOpro products, or when migrating from Silicon Labs' legacy isolators, designers must
consider and adhere to the following requirements.
3.1. 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.
3.1.1. Resolution
This issue has been corrected with Revision B of the device. Refer to the Ordering Guide for more information.
3.2. Latch Up Immunity (Revision A Only)
ISOpro latch up immunity generally exceeds ± 200 mA per pin. Exceptions: Certain pins provide < 100 mA of latch-
up immunity. To increase latch-up immunity on these pins, 100  of equivalent resistance must be included in
series with all of the pins listed in Table 13. The 100  equivalent resistance can be comprised of the source
driver's output resistance and a series termination resistor.
3.2.1. Resolution
This issue has been corrected with Revision B of the device. Refer to "5. Ordering Guide" on page 29 for more
information.
