Texas Instruments NE555 Precision Timers IC (SMD Package)

The NE555 Precision Timer ICs are precision timing circuits capable ofproducing accurate time delays or oscillation. In the time-delay or mono-stable mode of operation, the timed interval is controlled by a single externalresistor and capacitor network. In the a-stable modeof operation, the frequency and duty cycle can becontrolled independently with two external resistorsand a single external capacitor.
