Silicon die of the first 555 chip (1971) Die of a CMOS NXP ICM7555 chip. The timer IC was designed in 1971 by Hans Camenzind under contract to Signetics. [3] In 1968, he was hired by Signetics to develop a phase-locked loop (PLL) IC. He designed an oscillator for PLLs such that the frequency did not depend on the power supply voltage or ...
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. Camenzind also wrote three books and numerous technical articles, [3] and lectured at the University ...
Bare silicon chip, an early chip-scale package CSP: Chip-scale package: Package size is no more than 1.2× the size of the silicon chip [16] [17] TCSP: True chip-size package: Package is same size as silicon [18] TDSP: True die-size package: Same as TCSP [18] WCSP or WL-CSP or WLCSP: Wafer-level chip-scale package
Signetics Corporation was an American electronics manufacturer specifically established to make integrated circuits. [1] Founded in 1961, they went on to develop a number of early microprocessors and support chips, as well as the widely used 555 timer chip.

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 ...
