555/556 Timer
The 555 timer is one of the most used and useful ICs ever produced. Designed in 1971 by Hans Camenzind it provides a way to include different methods of timing and oscillation into your circuits.
InĀ the time delay mode the time isĀ precisely controlled by one external resistor andĀ capacitor.Ā In oscillator mode the frequency and duty cycle areĀ controlled with two externalĀ resistors and one capacitor.
- Ideal for use in 5V circuits
- Multiple modes:
- Astable: square wave of configurable frequency
- Monostable: pulse of configurable durationĀ on trigger
- Bistable: output dependant on two input states
- Inverting buffer: output is opposite of input
- Can be used with breadboard and perfboard easily
Available in both a single (555) and dual (556) package. The dual package contains two 555 timers which share common ground and source pins.
