The 555 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 monostable mode of operation the time is precisely controlled by one external resistor & one capacitor. For stable operation as an oscillator the free running frequency & the duty cycle are both accurately controlled with two external resistors & one capacitor. The circuit may be triggered & reset on falling waveforms & the output structure can source or sink up to 200m A or drive TTL directly. This IC may also be correctly supplied marked as MC1455PI. Supply decoupling must be provided close to the IC to counter the crowbar effect of the devices internal discharge switch a suitable value is 10 to 100micro F as shown in the accompanying diagrams. Monostable Mode Time Delay vs Rltsubgt Altsubgt & COn time after triggering i.e. applying a voltage to pin 2 less than 13 supply voltage is equal to 1.1RAC. The load may be connected to VCC for normally-on operation or between pin 3 & ground for normally- off. Connecting reset to ground during on time drives the output low until a new trigger pulse occurs. Additional trigger pulses during on time have no effect. If reset is not being used connect it to VCC. Astable Mode Oscillator Free Running Frequencyvs Rltsubgt Altsubgt Rltsubgt Bltsubgt & CThe frequency is equal to 1.44RA 2RBC.
