The title SDLS185 is only a literature code, so this 452 KB PDF datasheet does not reveal its component from the name alone. Texas Instruments uses SDLS numbers for many of its logic family datasheets, and the first page will state the exact device. Content normally includes absolute maximum ratings, recommended conditions, switching times and a pin diagram. Use it to confirm correct orientation and supply levels, and to rule out a failed logic chip before moving on to other parts of a faulty circuit.
