LM555/LM555C

Timer

General Description

The LM555 is a highly stable device for generating accurate

time delays or oscillation. Additional terminals are provided

for triggering or resetting if desired. In the time delay mode of

operation, the time is precisely controlled by one external re-

sistor and capacitor. For astable operation as an oscillator,

the free running frequency and duty cycle are accurately

controlled with two external resistors and one capacitor. The

circuit may be triggered and reset on falling waveforms, and

the output circuit can source or sink up to 200 mA or drive

TTL circuits.
