How are IC chip pins numbered?
How are IC chip pins numbered?
Pin numbers The pins are numbered anti-clockwise around the IC (chip) starting near the notch or dot. The diagram shows the numbering for 8-pin and 14-pin ICs, but the principle is the same for all sizes.
How do I read my IC chip number?
Read the serial number from the top side of the IC. The top side of the IC is facing up when the chip is standing on its pins. You may require a magnifying glass while reading the IC serial information.
What is the output pin of the IC?
Most integrated circuits typically have a ground pin. Pin 2 – The trigger pin is the input. When this pin gets connected to ground, it triggers the output to turn on at the supply voltage. Pin 3 – The output is where the result of the chips inner workings is output.

What’s the purpose of counting pins on an IC?
The main idea behind counting pins on IC, is to identify Pin No 1 on an IC. If you understood how to identify Pin Number 1 of a IC, you can read all the rest. I hope you found this article on Counting Legs or Pins of IC useful. Do share your thoughts below. Thanks!
How are pins numbered on an integrated circuit?
This comes from the old tube days where pins were numbered clockwise looking at the bottom of the tube, as you would when wiring up a socket. Just like with the old tubes, there is something on the package which marks one place a bit more special than the others. This is where you start counting from 1 going around the chip.
Where are the dot and notch on a circuit chip?
A dot can be in the pin 1 corner. A notch can be at the pin 1 end. Actually thinking back to the tube convention, the notch is really showing you where the start/stop gap in numbering is when going around the chip. This is totally consistent with tube pin numbering.
