PCN Details
Description of Changes: Silicon Labs is pleased to announce the full production release of erratafree revisions of all members of the Si84xx ISOpro family of 2.5 kVrms and 1 kVrms digital isolators.
Previous revisions (A and C) will continue to be supported in production for existing designs
and customers.
The new production revisions (B and D) are strongly recommended for all new designs and
production volumes.
Pricing for the new B and D revisions is unchanged from the previous A and C revisions.
See below for examples. Refer to the "Ordering Guide" section in each datasheet for all valid and
recommended Ordering Part Numbers (OPNs).

This PCN and production silicon release includes the following updates:
1) All known errata have been eliminated, as reflected in the revised datasheets posted at
www.silabs.com.
The enable pin functionality has been corrected.
The power supply ramp time issue when Vdd ≥ 4.5 V has been corrected.
Latch-up immunity has been improved, eliminating the need for additional series resistors.
2) Various specifications in the datasheets have been updated to better reflect production silicon
performance and characterization data.
The "Errata and Design Migration Guidelines” section has been updated to indicate the
elimination of all errata on Revision B and D silicon.
The "Ordering Guide" sections have been updated to include the new, errata-free silicon
revisions.
Supply currents and channel-channel skew specifications have been tightened.
The absolute maximum supply voltage has been improved from 5.75 to 6.0 V.
Clearance and creepage specifications have been clarified and improved.
The typical CMTI specification has been updated to 25 kV/μs versus the previous 30 kV/μs.
The output impedance specification has been corrected. The correct nominal value is 85 Ω
versus the previously-specified 50 Ω.
The logic low output voltage specifications have been revised for the Si840x I2C devices.
A new OPN has been added to the Si840x I2C family: Si8401. See datasheet for more details.
Reason for Change: This PCN is being issued due to the full production release of errata-free
silicon which is now strongly recommended for all new customer designs and production volumes.
The previous revisions will continue to be supported for existing customer designs. Customers are
strongly encouraged to migrate to revisions (B and D) to take advantage of the benefits of these
newer revisions.

Impact on Form, Fit, Function, Quality, & Reliability:
Form & Fit impacts: All devices listed in the updated Ordering Guide tables in the
datasheets are package and pinout compatible with the previous revisions.
Functional impacts: Revisions B & D change and correct the enable pin functionality (i.e.
the outputs will now go into the high-impedance state to match the legacy isolator
products).
Quality and Reliability impacts: Revisions B & D eliminate the power supply ramp up time
and latch up immunity errata. See the datasheets for more details.
See Description of Changes section above for datasheet specification change information.
Product Identification: The product revisions can be identified by the device top mark. Examples
for each of the 3 package types are shown below. Refer to the datasheets for additional
information.
8-pin SOIC: The character in the “R” position in the second row reflects the product revision.
16-pin Narrow & Wide Body SOICs: The character in the first “T” position on the second row
reflects the product revision.
Last Date of Unchanged Product: Not applicable.
Previous revisions (A and C) will continue to be supported in production for existing designs
and customers.
The new production revisions (B and D) are strongly recommended for all new designs and
production volumes.
Refer to the "Ordering Guide" section in each datasheet for all valid and recommended Ordering
Part Numbers.
Qualification Samples: Samples are available now upon request.
Qualification Data: Please see Appendix A for the Qualification Report.
