In this video, the brief introduction to the 555 Timer IC has been given and the pin diagram (of 8 pin DIP 555 IC) and the internal block diagram of the 555 timer have been explained. By watching this video you will learn the following topics: 0:20 Introduction and Application of 555 timer IC 0:50 Pin Diagram of 555 Timer IC 1:06 Internal Block Diagram of 555 Timer 1:48 Brief description of 8 Pins and basic working of the internal blocks of 555 timer what is 555 Timer IC? The 555 timer IC is a very popular timer IC and it is widely used in many timing related applications. It can be used as an oscillator, LED Flasher, tone generator, Frequency division, and timing delay generation. The 555 timer IC is available in many packages but most popular is 8 pin DIP (Dual Inline Package). The following is the list of the individual pin of 555 timer IC. 1. Ground 2. Trigger 3. Output 4. Reset 5. Control 6. Threshold 7. Discharge 8. Vcc In this video, the brief description of each pin is given. If you see the internal block diagram of 555 timer IC then it consists of the following parts. 1. Voltage Divider Circuit 2. Comparator 3. SR Flip-Flop 4. Discharge Circuit 5. Output Driver Circuit In this video, the function of each block is explained in detail. By connecting the external resistors and capacitor to the different pin of this 555 timer IC, it can be configured as either Astable, Monostable or Bistable Multivibrator and can be used in wide range of timing related applications. This video will be helpful to all the students of science and engineering in understanding the basic working of 555 timer IC. #555Timer #PinDiagram #InternalBlockDiagram Follow me on YouTube: null Follow me on Facebook: https://www.facebook.com/ALLABOUTELECRONICS/ Follow me on Instagram: https://www.instagram.com/all_about.electronics/ Music Credit: http://www.bensound.com/
