Texas Instruments LM555
The LM555 is a highly stable device for generating accurate time delays or oscillation. For a stable 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.| Part No. | LM555 |
