Schematic of a 555 timer in astable mode with a 1N4148 diode to create a duty cycles less than 50% Resistor R 1 {\displaystyle R_{1}} requirements: The maximum current through R 1 {\displaystyle R_{1}} must be lower than the maximum current rating of the internal transisor at the DISCHARGE pin, because this transistor "shorts" the DISCHARGE pin ...

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. It consisted of two vacuum tube ...
