What is pin diagram of 555 timer?

Pin diagram and description

Pin Name

How does IC pin work?

By convention, the pins on an IC are numbered counterclockwise, starting with the upper-left pin closest to the clocking mark. So, for example, with the clocking notch orienting the chip at the 12 o’clock position, the pins of a 14-pin IC are numbered 1 through 7 down the left side and 8 through 14 up the right side.

What is pin configuration?

Configuration pins are used to load the design data into SRAM-based FPGAs. The bitstream defines the functional operation of the internal resources, interconnections and I/O for the FPGA. The configuration mode selected to program the FPGA is an important design factor to consider when assigning pins.

How do I read my IC pin?

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.

What does pin 1 do on a 555 timer?

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.

Why the control voltage pin pin 5 of 555 timers is connected to ground through a 0.01 ΜF capacitor?

The control pin on the 555 timers is normally connected to the ground through a capacitor (∼ 0.01μF because the noise from the supply line can ride through this simple divider adding small capacitor filters out high-frequency noise that can cause the comparison point to vary slightly.

Which pin on an IC is 1?

Pin 1 is on the lower left hand side. If you look very closely, you’ll see that there is one additional polarity marking feature, in that this chip also has a very slightly beveled front edge. This is a somewhat unusual seven-yes-seven pin DIP chip.

Which pin is pin 1?

Note that the lower right-hand pin of each connector is a square solder joint on the motherboard, designating Pin 1. These connectors are for (top to bottom) the primary and secondary IDE controllers, and the floppy disk controller.

Why is 555 timer IC so important?

The 555 timer IC is an integral part of electronics projects. Be it a simple project involving a single 8 bit micro-controller and some peripherals or a complex one involving system on chips (SoCs), 555 timer working is involved. These provide time delays, as an oscillator and as a flip-flop element among other applications.

What activates the 555 IC timer?

– Pin 1. – Ground, The ground pin connects the 555 timer to the negative (0v) supply rail. – Pin 2. – Trigger, The negative input to comparator No 1. – Pin 3. – Output, The output pin can drive any TTL circuit and is capable of sourcing or sinking up to 200mA of current at an output voltage equal to – Pin 4. – Pin 5. – Pin 6. – Pin 7. – Pin 8.

What is 555 timer IC and how it works?

So capacitor discharges and that’s why output is low.

  • When negative trigger pulse is applied,the trigger comparator gives high output.
  • So output becomes high and discharging transistor becomes off.
  • So again capacitor starts charging towards Vcc.
  • So the output becomes high only when trigger is applied and remain high till capacitor charges to 2/3 Vcc.
  • How to make a transistor tester using 555 timer IC?

    Solder the NE555 timer IC on the veroboard. After that,short pin 4&8 of the IC.

  • Solder a 33K Ohm resistor between pin 2&3 of the IC.
  • Solder the female header pins on the veroboard.
  • After that,solder a 220 Ohm resistor between pin 3 and pin 8 of the IC.
  • Solder the cathode pin of one 1N4007 diode with the anode pin of the other.
