The 555 timer IC is an integrated circuit used in a variety of timer, ... In 2006, the dual 556 timer was available in through-hole packages as DIP-14 ...
The stepped-tone generator [49] is a circuit that utilizes a 556 dual timer IC. The controls are two potentiometers. Mims titled the circuit "Sound Synthesizer" in 1982 [50] then later called "Stepped-Tone Generator". The circuit creates sounds similar to a plucked violin. [49]
Its engineers continued to innovate in IC technology, and remained a significant force. Around 1971, the Signetics introduced the innovative 555 timer IC, which it called "The IC Time Machine". [2] This was the first and only low-cost commercial IC timer available at the time, and soon became a best-seller.
Hans R. Camenzind (Swiss Standard German: [ˈkaːməntsɪnd]; 1 January 1934 – 8 August 2012 [1]) was an electronics engineer known for designing the 555 timer IC in 1971 under contract to Signetics. [2] He was the inventor on 20 US patents.
In the release dates, the 555 was released also in a 14 pin DIP. The article calls this a 556, which came later. 2A00:23C7:F583:3501:1B6E:666B:EEA1:CA64 16:42, 27 February 2024 (UTC) Please post a link to proof to back up this claim. • Sbmeirow • Talk • 06:41, 28 February 2024 (UTC)

The following is a list of CMOS 4000-series digital logic integrated circuits.In 1968, the original 4000-series was introduced by RCA.Although more recent parts are considerably faster, the 4000 devices operate over a wide power supply range (3V to 18V recommended range for "B" series) and are well suited to unregulated battery powered applications and interfacing with sensitive analogue ...
