Additional Information


555 Timers 8 Pin DIP

The LM555 is a highly stable device. It is used for generating precise time delays or oscillation.

There are additional terminals for triggering or resetting if desired. In the time delay mode, the time is accurately controlled by one external resistor and capacitor. As an oscillator, in a stable operation the free running frequency and duty cycle are precisely controlled with two external resistors and one capacitor.

The circuit of the LM555 may be triggered and reset on falling waveforms, and the output circuit can sink up to 200mA or drive TTL circuits.
