rdfs:comment
The 555 timer IC is an integrated circuit (chip) used in a variety of timer, pulse generation, and oscillator applications. The 555 can be used to provide time delays, as an oscillator, and as a flip-flop element. Derivatives provide up to four timing circuits in one package.Introduced in 1971 by American company Signetics, the 555 is still in widespread use due to its low price, ease of use, and stability.
