The 555 IC timer does not have a clock.
556 is a dual version of 555 single timer.
555 timer is used to generate clock signals in the ic 555 timer the pin no 8 is represents vcc
The 555 is a timer, not a counter.
555 is an arbitrarily assigned part number for a general purpose programmable timer IC. The number itself has no special meaning.
8-pin 555 timer IC
its cheap and easy to use.
The 555 timer IC is an integrated circuit ,that is used mainly in a variety of timer, pulse generation, and oscillator applications. It can be used to provide time delays.
arbitrary part ID number
The 555 IC is a universal timer circuit. Via the addition of external components (resistors, capacitors) the designer can generate various timing waveforms.
there are 3 resistors of 5k each...hence the name 555
Go to Place -- Components ---- Find "Mixed" in Groups --- and write 555 in components text bar, here u have IC 555
