Technical documentation and image source
The complete ordering code, description, package and published temperature fields use the linked manufacturer evidence. Temperature fields retain their stated source definition; application limits and test conditions follow the linked datasheet. Pin count uses the manufacturer terminal numbering of the identical literal package; a tab or exposed pad may share a terminal number. Images are authorized-distributor package references, not current-lot photographs or guaranteed top marking. No certification is inferred from a suffix. Image source is the explicitly linked authorized DigiKey product reference, independently matched to the original manufacturer package/pin drawing. Manufacturer product page currently provides only a placeholder. Native pixel dimensions are retained; no artificial enlargement or exact-lot marking claim.
