Designed in 1971 by Hans Camenzind it provides a way to include different methods of timing and oscillation into your circuits.\u003c\/p\u003e\n\u003cp\u003eIn the time delay mode the time is precisely controlled by one external resistor and capacitor. In oscillator mode the frequency and duty cycle are controlled with two external resistors and one capacitor.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eIdeal for use in 5V circuits\u003c\/li\u003e\n\u003cli\u003eMultiple modes:\u003c\/li\u003e\n\u003cul\u003e\n\u003cli\u003eAstable: square wave of configurable frequency\u003c\/li\u003e\n\u003cli\u003eMonostable: pulse of configurable duration on trigger\u003c\/li\u003e\n\u003cli\u003eBistable: output dependant on two input states\u003c\/li\u003e\n\u003cli\u003eInverting buffer: output is opposite of input\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cli\u003eCan be used with breadboard and perfboard easily\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eAvailable in both a single (555) and dual (556) package.
