What is 555 timer explain its pin configuration?
The 555 timer IC consist of 8-pins where each pin has some function. The pin configuration of this IC is shown below. Pin-1 is a GND pin which is used to supply a zero voltage to the IC. Pin-2 is a trigger pin which is used to convert the FF from set to RST (reset).
What is the function of pin number for of the IC 555?
Pin 2: Trigger Terminal: The trigger pin is used to feed the trigger input hen the 555 IC is set up as a monostable multivibrator. This pin is an inverting input of a comparator and is responsible for the transition of flip-flop from set to reset.
What Is pin number 8 in 8-pin DIP IC 555?
Pin 8 – Supply voltage (VCC) This is the positive supply voltage terminal of the IC. The supply voltage range vary between +5V and +15V. The RC timing interval will not much vary over the supply voltage range (approximately 0.1%) in either astable or monostable mode.
Which is the output pin number IC 555 timer?
pin 3
The output (pin 3) of the standard 555 timer or the 556 timer, has the ability to either “Sink” or “Source” a load current of up to a maximum of 200mA, which is sufficient to directly drive output transducers such as relays, filament lamps, LED’s motors, or speakers etc, with the aid of series resistors or diode …
What is the output pin number of IC 555 timer?
As explained in the tutorial, a 555 timer IC output pin (pin 3) is capable of both sinking and sourcing a connected load up to about 200mA. A HIGH output condition (source) is able to drive an external npn transistor, while a LOW output condition (sink) is able to drive an external pnp transistor.
How do I find my IC pin number?
Pin numbers The pins are numbered anti-clockwise around the IC (chip) starting near the notch or dot. The diagrams show the numbering for 8-pin and 14-pin ICs, but the principle is the same for all sizes.
