SDLS196 is the literature code on this 430 KB PDF datasheet, which gives no part number in its name. The SDLS pattern is associated with Texas Instruments logic literature, so expect a logic device whose identity is shown on the title page. Contents generally include pinout, logic diagram, electrical limits and timing data. A technician uses them to confirm correct input and output behaviour on a board and to choose a replacement. Compare the marking on the IC with the part described before probing.
