555 Timer IC
- A 555 timer IC is an integrated circuit used in timer, pulse generation, and oscillator applications.
- It can provide time delays, act as an oscillator, and as a flip-flop element.
- Derivatives provide up to four timing circuits in one package.
555 Timer IC Operating Modes
- Monostable mode: produces one pulse of a set length in response to a trigger input.
- Astable mode: produces a continuous oscillation.
