National Semiconductor part numbers

National Semiconductor (LM op amps and regulators, LMV/LMH/LMP amplifiers, LP power ICs, DS90 LVDS, DP83 Ethernet PHYs, ADC08/ADC12 converters) was acquired by Texas Instruments in 2011.

National Semiconductor is now Texas Instruments (2011). We quote National Semiconductor parts — current, obsolete and end-of-life — and parts that carry older National Semiconductor markings. See also all Texas Instruments part numbers.
