Component datasheet saved as a 197 KB PDF under the literature number SDLS946. The SDLS prefix is commonly seen on Texas Instruments logic documentation, but the file name itself does not state which device is covered, so check the first page. Logic datasheets of this kind give the function table, pinout, propagation delays and supply ranges, useful when verifying a gate or buffer on a board. Make sure the logic family and package on the PCB match those described before substituting a part.
