3 Description
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.
