Motorola Semiconductor part numbers

Motorola spun off its discrete, standard logic and analog business as ON Semiconductor (now onsemi) in 1999 and its microcontroller and processor business as Freescale (now NXP) in 2004. MC-prefixed part numbers continue at both.

Motorola Semiconductor is now onsemi and NXP Semiconductors (1999 / 2004). We quote Motorola Semiconductor parts — current, obsolete and end-of-life — and parts that carry older Motorola Semiconductor markings.

Frequently asked questions

Is Motorola Semiconductor still in business?

Motorola spun off its discrete, standard logic and analog business as ON Semiconductor (now onsemi) in 1999 and its microcontroller and processor business as Freescale (now NXP) in 2004. MC-prefixed part numbers continue at both.

Can I still buy Motorola Semiconductor parts?

Yes. PartnerSemi quotes Motorola Semiconductor part numbers, including obsolete and end-of-life parts and parts with old Motorola Semiconductor markings. Send the part number and quantity; we reply with price, lead time, date code and origin. We are an independent distributor, not an authorized Motorola Semiconductor or onsemi and NXP Semiconductors distributor.
