A 303 KB PDF datasheet labelled with the literature code SDLS182 and nothing more descriptive. Texas Instruments assigns SDLS numbers to standard logic datasheets, so the document likely covers one logic IC whose identity is printed on page one. Look for the connection diagram, function table and DC and AC characteristics. During repair, these pages let you check the correct VCC and GND pins, compare probed levels with expected behaviour, and confirm pin compatibility of any substitute you plan to fit.
