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.

Forrest M. Mims III is an American amateur scientist, [2] magazine columnist, and author of Getting Started in Electronics and Engineer's Mini-Notebook series of instructional books that were originally sold in Radio Shack electronics stores and are still in print.
The TK-80 has the Dynamic Display using the 555 timer IC and interrupt the CPU, it can always show the current address. In addition, the TK-80 has a CMOS battery. He decided to document its manual with a circuit diagram and assembly code of the debug monitor, influenced by the PDP-8 which was an open architecture and was used as an IC tester at ...
The reissued EX-150 sold well enough to justify an expansion kit. It is designed for the reissued EX-150 only and, allegedly, will not work with the original. The expansion contains components for performing optical experiments, including LED blocks, optical fibres and a 555 timer IC block. As some of the experiments involve two separate ...
