What does pin 5 do on a 555 Timer?
Control: Pin 5 is the control pin. In most 555 circuits, this pin is simply connected to ground, usually through a small 0.01 μF capacitor. (The purpose of the capacitor is to level out any fluctuations in the supply voltage that might affect the operation of the timer.)
Why IC is called 555?
The 555 Timer IC got its name from the three 5KΩ resistors that are used in its voltage divider network. This IC is useful for generating accurate time delays and oscillations.
Where are 555 timers used?
The standard 555 timer IC is used in a variety of timer, pulse generation and oscillator applications. It can be used to provide time delays, as oscillators and as flip-flop elements. The 555 timer IC is an integral part of electronics projects.
How many different 555 timers are there?
There are two types of 555 timer based on its nomenclature – NE 555 Timer and SE 555 Timer. While NE 555 timer can be used in the temperature range from 0 to 70°C, the SE 555 Timer can be used in the temperature range from -55°C to 125°C and has a temperature stability of 0.005% per 0C..
What is inside a 555 timer?
Here’s the internal schematics of 555 Timer which consists of 25 transistors, 2 diodes and 15 resistors. Represented with a block diagram it consists of 2 comparators, a flip-flop, a voltage divider, a discharge transistor and an output stage.
What is the function of IC 555?
