A 706 KB PDF datasheet identified only by the literature code SDLS192, with no part number or device name in the title. The SDLS series is the numbering Texas Instruments applies to many standard logic datasheets, so this is most likely one of those chips, but the cover page must confirm it. Expect package drawings, pin assignments, function tables and electrical limits. When diagnosing a board, compare measured input and output states with the function table and make sure the package code matches before ordering a substitute.
