Frequently asked questions

Is Catalyst Semiconductor still in business?

Catalyst Semiconductor (CAT24/CAT25 EEPROM, CAT LED drivers and supervisors) was acquired by ON Semiconductor (now onsemi) in 2008.

Can I still buy Catalyst Semiconductor parts?

Yes. PartnerSemi quotes Catalyst Semiconductor part numbers, including obsolete and end-of-life parts and parts with old Catalyst 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 Catalyst Semiconductor or onsemi distributor.
