It was commercialized in 1972 by signetics. Pin 2 trigger tri a low voltage less than 1 3 the supply voltage applied momentarily to the trigger input causes the output pin 3 to go high. Numerous companies have made the original bipolar timers and similar low power cmos timers too.
The 555 timer is a simple integrated circuit that can be used to make many different electronic circuits.
The 555 timer ic is an integrated circuit used in a variety of timer delay pulse generation and oscillator applications. The 555 timer ic is an integral part of electronics projects. The lm555 are available in 8 pin pdip soic and vssop packages and is a direct replacement for se555 ne555. Generally it is a monolithic timing circuit that gives precise and highly stable delays of time or oscillation.
