The LM555-MIL 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 resistor and capacitor.
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.
