Hello guys,
One of my customers is using SN74LV164A for their mass production.
At this moment, they have the following questions.
Could you please give me your reply?
Q.
Recently, the device datasheet is modified from version SCLS403J to SCLS403K.
SCLS403K says the following about modified points.
>Changes from Revision J (December 2022) to Revision K (March 2023)
> • Updated the structural layout of document
> • Updated thermal values for D package from RθJA = 92.6 to 112.9,
RθJC(top) = 53.9 to 68.7, RθJB = 46.8 to 69.4, ΨJT = 18.9 to 30,
ΨJB = 46.6 to 69, all values in °C/W
But we can see that D package thermal information in version K is same as version J
and PW package one is different from version J.
Which is correct for the new datasheet?
Your reply would be much appreciated.
Best regards,
Kazuya.
