The 555 is an There was an error working with the wiki: Code[9] (chip) implementing a variety of There was an error working with the wiki: Code[10] and There was an error working with the wiki: Code[11] applications.

Decription

in There was an error working with the wiki: Code[3]]]

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

These specifications apply to the NE555. Other 555 timers can have better specifications depending on the grade (military, medical, etc).
