PCA9546A: Wrong dimensions is EasyEDA? (LCSC store)

Yigal BenZeev

Part Number: PCA9546A

Tool/software:

i would like to use PCA9546A in SOIC-16 package (sadly no DIP is available).

It seems there are 3 SOIC-16 packages in the data sheet packaging - I assume the difference is due to different quantity, yet it is exactly the same part, correct?

So I looked in LCSC store from the EasyEDA, and got this device:

https://www.lcsc.com/product-detail/Interface---Specialized_Texas-Instruments-PCA9546ADR_C2674051.html

i noticed several differences, such as:

Width of end pad to end pad in datasheet is: 10.63 mm, while in PCB layout it is 7.3mm

package only width (without pads) should be 7.6, while in layout: 3.0

Ami right or am i missing anything?

Does TI provide layout models for EasyEDA?

That could be very helpful, especially if these models would include static and dynamic behavioral models.

Thank you

Where are you seeing three SOIC packages? The PCA9546A is available in the D and DW packages. They are specified on the TI web page. For footprints, see the "Ultra Librarian" link in the "Design & development" section on the product page.

Now I am confused.

The data sheet here species 3 SOIC parts: DR, DW, DWR. (DR is active, not really matters to me, should it?)

I assume they all have same foot print on the PCB, is that correct?

About the Ultra Librarian - this looks great, as it includes also 3D model. But it seems that EasyEDA can't read it.

i read in their forum that it should be "exported to kicad" . I am now trying to import it.

D and DW are packages. The R suffix indicates a large reel.
