555 Ic Chip Definition. The 555 integrated circuit acts as a counter. Second we cannot draw more than 100ma from the chip.
The output circuit is capable of sinking or sourcing current up to 200 ma. This usually activates other components such as leds or relays. Ic 555 is the most versatile chip and it is can be used in all most every kind of application because of its multi functionality.
The 555 is a single chip version of a commonly used circuit called a multivibrator which is useful in a wide variety of electronic circuits.
Although these loads are normally non inductive types an inductive load like a relay can be also effectively used directly across pin 3 and ground as shown in the following diagrams. In 2017 it was said over a billion 555 timers are produced. Important characterstics of 555 timer ic. The ic 555 allows the use of loads with maximum current specifications of up to 200 ma.
