11+ 555 Timer Pin Diagram. You may already know that se/ne 555 is a timer ic introduced by signetics corporation in 1970's. The 555 timer ic is available in many packages but most popular is 8 pin dip (dual inline package).
In most 555 circuits, this pin is simply connected to ground, usually through a small 0.01 μf capacitor. For the timer to function to work, this pin must be connected to positive voltage of range +3.6v to +15v. In astable mode, the 555 how astable mode works.
This article covers every basic aspect of 555 timer ic.
11+ 555 Timer Pin Diagram. Derivatives provide two (556) or four (558) timing circuits in one package. Let us look at the pin diagram to have an idea. Time constants i timing from microseconds through hours i operates in both astable and monostable modes i adjustable duty cycle i high output general purpose cmos timer. This means it has 8 different pins, each of which have different functions for the ic.
