Corporate information

Founded in 1961 by former Fairchild employees, Signetics Corporation produced a wide range of integrated circuits, including bipolar and MOS parts. Around 1971, the Signetics Corporation introduced the 555-timer circuit. It was called "The IC Time Machine". It was also the first and only commercial IC timer available at the time.

In 1975 Signetics was purchased by Philips. Philips continued to use the Signetics brand name until 1992. Signetics became a Philips independent subcontract service provider in 1995.

Korean company Young Poong Electronics Corporation acquired Signetics in 2000 as a major shareholder.
