The 555 timer IC is an integrated circuit used in a variety of timer, delay, ... Monostable (one-shot) mode – The 555 operates as a "one-shot" pulse generator ...
A vacuum tube Abraham-Bloch multivibrator oscillator, France, 1920 (small box, left).Its harmonics are being used to calibrate a wavemeter (center).. The first multivibrator circuit, the classic astable multivibrator oscillator (also called a plate-coupled multivibrator) was first described by Henri Abraham and Eugene Bloch in Publication 27 of the French Ministère de la Guerre, and in ...
The trigger is toggled high when the input voltage crosses down to up the high threshold and low when the input voltage crosses up to down the low threshold. Again, there is a positive feedback, but now it is concentrated only in the memory cell. Examples are the 555 timer and the switch debouncing circuit. [3]

English: The NE555 contains 24 bipolar transistors, two diodes and 15 resistors that form six functional blocks: Between the supply voltage VCC (+) and the ground GND (-) is a voltage divider consisting of three identical resistors which, when connected not from the outside, the two reference voltages ¹ / 3 VCC and ² / 3 VCC supplies.
Nearly one in five adults “who say they have no personal or family history of heart attack or stroke,” reported in the survey that they “routinely” took a low-dose aspirin, with 10% saying ...
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 ...
