Datasheet issue. TDA7266 STI Pinout shows even pins as lonng when in fact tehy are the inner shorter pints
Would you have an image showing this with items you got on hand?
The package drawing on p.13 indicates that the “short” pins as drawn are those which protrude from the package plane, and are odd numbered.

This is the same package; I am waiting for the exact part. Notice that the long pins are on the outside ends of the package not the short pins as shown on the diagram.
Thanks. I found this but it is not the STI data sheet that you publish which shows quite the opposite.

Can you provide that datasheet? doing a search for the terms TDA7266 and STI do not return any results for me.
The picture I provided is located in Figure 6, Page 8 of the datasheet.
That is ridiculous. Have you checked your own catalog?
From your product listing website, the picture which shows the part with the longer pins at the outside extensions, not what the data sheet implies.
And this is the datasheet from your website;

A reference to “short” or “long” here might be variably interpreted as a reference to the appearance in the 2D package drawing, or to the running length of a physical protuberance from the package body. Dimension “L” above is “short” relative to dimension “L1”, despite referencing a conductor of greater overall length.
Similarly, the reference to “STI” might be interpreted as a reference to the manufacturer, but just as easily as a reference to a part number suffix (not listed at DigiKey) that could potentially refer to a device package variant.
The device in the provided photo appears to have leads terminating normal to the package plane while the linked datasheet shows a package with leads ending parallel to that plane. Some misapprehension of matters when comparing the device pictured to the right-hand view of figure 16 above could be understandable.
I suspect you may have an example of an alternative lead conformation available in prior years when devices of the type were more popular, but which is no longer available/documented in the current datasheet revision.
Nice thought, but the photo on your data sheet is the same as the one that I provided except mine is a little bit clearer so this is discrepancy on the data sheet between the photo and the diagram remember that that data sheet is from your catalog directly
The following illustrations from the datasheet are the best representation of how Part Number TDA7266 would come supplied from DigiKey.
The odd numbered pins are bent forward and then down, the pins orientation to the circuit board is parallel to the metal tab.
As Rick has mentioned your pictured part may be either modified to orientate a different way or a version of the part that is no longer available.

Thank you. That is a much clearer presentation. The parts diagram still does not do much to be definitive. They probably should be a drawing facing down on the pins to make it perfectly clear. Thanks again.
