PDF datasheet with the literature code SDLS163, 303 KB in size. The name does not mention the device, only a number in the series Texas Instruments uses for standard logic data sheets, so look at the title block to learn which part it covers. The usual content includes the pinout, function table, voltage and current limits and outline drawings. It helps when tracing signals through a logic IC or confirming which pin is VCC. Match the chip marking with the document before relying on it.
