SN74LV4052A-Q1: Some of the spec have changed since revision G?

Part Number: SN74LV4052A-Q1
Other Parts Discussed in Thread: SN74LV4052A

Tool/software:

Hello,

My customer has been using SN74LV4052A-Q1.  The PCN(20240613005.2) and the revision history shown in the datasheet don't seem to have changed elecrtrical characteristics, but if I look at the datasheet from revision G carefully, it looks some have changed for Ta=85-105degC like below.  Am I correct?  Do you have summary of the changes by any chance so that my customer can find all the items they need to check?

- Control input current until revision F

- Control input current from revision G

Best regards,

Yoshikazu Kawasaki

    .Hi Yoshiazu,

    So the main note in the revision history between Rev F and Rev G if just a summary of the change made between the two revisions.

    Like I think you mentioned the electrical characteristics of this device look to not have been change it is just the formatting of the table that is different now

    For example the new sn74lv4052a datasheet has min and max ih and il control input data for three different temperature ratings.

    In addition the recommended temperature for the SN74LV4052A-Q1 is now -40 to 125C for all packages and instead of -40 to 105C for some packages and -40 to 125C for other packages.

    Overall the new SN74LV4052A-Q1 datasheet is a improvement over the older version(rev F).

    Please let me know if this helps you and I can explain or dig into this more if needed

    Regards,

    Hello Kameron-san,

    Thank you for your comments.

    Please let me ask you differently.  If my customer uses SN74LV4052-Q1 at 100degC, it usesd to be ±1uA, but is ±2uA, so the spec has changed.  Am I correct?  Do you have a list of the summary of the changes like this?

    Best Regards,

    Hi Yoshikazu,

    You are correct

    Thank you for pointing this out and our team is investigating this now.

    Is your customer using this device >85C<=105C?

    Is your customer requesting a comparison of the old and new datasheets? ( and if so when would they need something like that)
