The IC was designed and invented by There was an error working with the wiki: Code[4] units per year (There was an error working with the wiki: Code[5]). The 555 timer is one of the most popular and versatile integrated circuits ever produced. It includes 23 There was an error working with the wiki: Code[6]).

The 555 has three operating modes:

There was an error working with the wiki: Code[12] mode: in this mode, the 555 functions as a "one-shot". Applications include timers, missing pulse detection, bouncefree switches, touch switches, etc.

There was an error working with the wiki: Code[7] (PWM) etc.

There was an error working with the wiki: Code[8], if the DIS pin is not connected and no capacitor is used. Uses include bouncefree latched switches, etc.

Specifications
