MNLM555-X REV 0B0
PRECISION 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 resistor 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 200mA or drive TTL circuits.
