1.2 Base Part Numbers

The temperature range and channel count are used to create the base part number. The “-N” in a part name denotes devices acquired from National Semiconductor that matched an existing Texas Instruments (TI) base part number. There are no orderable part number duplicates because National Semiconductor and TI used different package suffixes. Some base numbers may include an 'A' at the end, but that does not affect the temperature range.

Part numbers in bold have operating temperature regions that match the given temperature range exactly. Part numbers that are not in bold can operate within and beyond the given temperature range. Please note that, counterintuitively, LM2904 is a dual op amp, whereas LM2902 is a quad op amp.
