In 1972, Signetics originally released the 555 timer in DIP-8 and TO5-8 metal can packages, and the 556 timer was released in a DIP-14 package. [ 4 ] In 2006, the dual 556 timer was available in through-hole packages as DIP-14 (2.54 mm pitch), [ 21 ] and surface-mount packages as SO-14 (1.27 mm pitch) and SSOP-14 (0.65 mm pitch).
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.
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.

Research and industry in this specialty continues to grow and prosper. Some examples of long-lived and well-known analog chips are the 741 operational amplifier, and the 555 timer IC. Power supply chips are also considered to be analog chips. Their main purpose is to produce a well-regulated output voltage supply for other chips in the system.
Note: 555 timer IC#Pinout writes them exactly how I want...a fully-spelled one-word name for each pin in all caps (except GND and VCC cause those are standard abbreviations). Em3rgent0rdr 02:59, 14 July 2022 (UTC) another inconsistency that is bugging me is how sometimes the trigger pin is written without a line over it but sometimes is.
A similar relaxation oscillator can be built with a 555 timer IC (acting in astable mode) that takes the place of the neon bulb above. That is, when a chosen capacitor is charged to a design value, (e.g., 2/3 of the power supply voltage) comparators within the 555 timer flip a transistor switch that gradually discharges that capacitor through a ...
