555 Chip Pinout. The 555 timer requires a power supply voltage of 4 5 16v. The chart below gives the identities of each of the pins and what function they play in a circuit.
The lm555 is a highly stable device for generating accurate time delays or oscillation. Numerous companies have made the original bipolar timers and similar low power cmos timers too. You may also occasionally use a 556 ic which consists of two 555 timers in a single package and the same applies to knowing its pinouts as well.
The output circuit is capable of sinking or sourcing current up to 200 ma.
Brief description on 555 timers. Additional terminals are provided for triggering or resetting if desired. The 555 timer ic is used in time delay circuits. About the book author.
