Semiconductor datasheet in PDF format, 438 KB, named by the literature number SDLS159. The file name is uninformative about the part itself; the SDLS series is used by Texas Instruments for standard logic documentation, and the covered device is named on page one. The sheet typically provides pinout, logic diagram, absolute maximum ratings and package drawings. Use it when tracing a signal path through a logic chip or locating power pins. Compare the chip marking with the document before replacing anything.
