The 555 timer IC is an integrated circuit used in a variety of timer, delay, pulse generation, and oscillator applications. It is one of the most popular timing ICs due to its flexibility and price. Derivatives provide two or four timing circuits in one package. [2]
English: The NE555 contains 24 bipolar transistors, two diodes and 15 resistors that form six functional blocks: Between the supply voltage VCC (+) and the ground GND (-) is a voltage divider consisting of three identical resistors which, when connected not from the outside, the two reference voltages ¹ / 3 VCC and ² / 3 VCC supplies.
