    The 555 timer datasheet specifies that 555 IC 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.

    Features from the 555 datasheet

    • Direct replacement for SE555/NE555
    • Timing from microseconds through hours
    • Operates in both astable and monostable modes
    • Adjustable duty cycle
    • Output can source or sink 200 mA
    • Output and supply TTL compatible
    • Temperature stability better than 0.005% per °C
    • Normally on and normally off output
    • Available in 8-pin MSOP package

        Check out the Firefly Flasher circuit that I submitted. It uses a variant of the 555 timer. All 555s have the same pin-out and function, but the modes of operation and applications vary greatly. The datasheets often offer numerous circuits.

      i want a project on real time application of ic 555.
      either it can work on pspice or on real hardware basis.
      please send it to my email id

      i will be highly obliged
      thank you

    8. plz giv the complete datasheet..

      1 doubt:: i came to knw ter are ics named
      NE/SA/SE555/SE555C and so..
      are they different?? plz rply.
