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 a stable operation as an oscillator, the free running frequency and duty cycle are accurately Output and Supply TTL Compatible controlled with two external resistors and one ?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.
