A low pulse on this pin (below 1/3 of VCC) sets the internal flip-flop and makes the output go HIGH. When the voltage on this pin reaches 2/3 of VCC, it resets the flip-flop, and the output goes LOW.

Modern power electronics are growing in both power capacity and density, making circuit protection more important than ever. There's increasing interest in solid−state circuit breakers and power ...

These days, if you want to flash some LEDs, you’d probably grab a microcontroller. Maybe you’d go a little more old-school, and grab a 555. However, [Jacob] is even more hardcore than that, as ...

The 555 timer is one of the most versatile integrated circuits available. It can generate PWM signals, tones, and single-shot pulses. You can even put one in a bi-stable mode similar to a flip flop.

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 ...

A Digital fundamentals project worked on fire alarm detector circuit which is build mainly using 555 Timer IC and implemented in Tinkercad ...

Abstract: This paper proposed a modified 555 timer IC with only two comparators by eliminating the discharge transistor and SR flip-flop. A periodic square waveform can be generated by utilizing the ...
