The 555 timer IC is an integrated circuit used in a variety of timer, delay, pulse generation, and oscillator applications. It is one of the most popular timing ICs due to its flexibility and price. Derivatives provide two (556) or four (558) timing circuits in one package. [ 2 ] The design was first marketed in 1972 by Signetics [ 3 ][ 4 ] and ...
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. Signetics was known for creating innovative ICs for both analog electronics and the rapidly-growing digital electronics ...
For example, the positive (and/or negative) pulse width from a 555 Timer IC in monostable or astable mode represents the time it takes to charge (and/or discharge) its capacitor from 1 ⁄ 3 V supply to 2 ⁄ 3 V supply. By sending this pulse into a microcontroller with an accurate clock, the duration of the pulse can be measured and converted ...
Multivibrator. A multivibrator is an electronic circuit used to implement a variety of simple two-state [1][2][3] devices such as relaxation oscillators, timers, latches and flip-flops. The first multivibrator circuit, the astable multivibrator oscillator, was invented by Henri Abraham and Eugene Bloch during World War I.
Relaxation oscillators are generally used to produce low frequency signals for such applications as blinking lights and electronic beepers. During the vacuum tube era they were used as oscillators in electronic organs and horizontal deflection circuits and time bases for CRT oscilloscopes; one of the most common was the Miller integrator circuit invented by Alan Blumlein, which used vacuum ...
Plastic leaded chip carrier (PLCC): square, J-lead, pin spacing 1.27 mm. Quad flat package (QFP): various sizes, with pins on all four sides. Low-profile quad flat-package (LQFP): 1.4 mm high, varying sized and pins on all four sides. Plastic quad flat-pack (PQFP), a square with pins on all four sides, 44 or more pins.
The Stylophone is a miniature analog electronic keyboard musical instrument played with a stylus. Invented in 1967 by Brian Jarvis, [ 1 ] it entered production in 1968, manufactured by Dubreq. Some three million Stylophones were sold, mostly as children's toys, but they were occasionally used by professional musicians such as John Lennon, [ 2 ...
A chase is an electrical application where strings of adjacent light bulbs cycle on and off frequently to give the illusion of lights moving along the string. With computerized lighting consoles, building chase sequences has become easier, while previously chases used mechanical means, such as a wheel with an electrified spindle which strikes electrical contacts for each circuit.
