3. Errata and Design Migration Guidelines
The following errata apply to Revision C devices only. See "5. Ordering Guide" on page 25 for more details. No
errata exist for Revision D devices.
3.1. Power Supply Bypass Capacitors (Revision C and Revision D)
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 D of the device. Refer to “5. Ordering Guide” for current ordering
information.
3.2. Latch Up Immunity (Revision C 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. The Si8410 is not affected by the latch up immunity
issue described above.
3.2.1. Resolution
This issue has been corrected with Revision D of the device. Refer to “5. Ordering Guide” for current ordering
information.
