In the storied history of electronics, very few components have managed to command the iconic status the 555 timer has enjoyed. Since its emergence in the early 1970s, this versatile integrated ...

The function of the 555 timer is mainly determined by two comparators. The output voltage of the them controls the state of the RS flip-flop and the discharge tube. It also contains 3 working states.

This article is part of the 2022 April 1st series in the Humor topic within our Series Library. The ubiquitous 1971 digital miracle—the 555 Timer—is important, replete with 25 transistors, 15 ...

If you’ve got a cheap ham rig, it might not be very practical for you to receive certain transmissions out of the box. However, if you were to hack in a convenient little beat frequency oscillator ...

IC NE/SE 555 is a highly stable device for generating accurate time delays. Commercially, this IC is available in 8-pin circular, TO-99 or 8-pin DIP, or 14-pin DIP packages. The salient features of ...

The 555 timer IC has been around now for quite some time and the list of potential uses for this device appears to be endless. This article contains a few examples of circuits that you might ...

If you’re not familiar with the 555 timer, suffice it to say that this versatile integrated circuit is probably the most successful ever designed, and has been used in countless designs, many of which ...
