Datasheet in PDF, 1.36 MB, carrying document code SDNS033B; the B suffix typically marks a revised edition. The name gives no information on the chip, brand or package, so identification has to come from the first page. A document of this length generally offers detailed block diagrams, pin descriptions and characteristic curves, all useful for working out how the part sits in a circuit and whether measured behaviour on a repair bench is normal.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @datasheet_technar_org. Enginerys does not host this file.
