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 ...

Probably not. Today almost everything is micro-based and SMT. If you need a multivibrator oscillator, you no longer go for the 555 timer IC. Instead, you program a cheap 8-bit PIC processor to do ...

The ubiquitous 1971 digital miracle—the 555 Timer—is important, replete with 25 transistors, 15 resistors, and two diodes uncomfortably crammed into an IC smaller than a dime (5 pence coin for ...

Smoothing down the copper traces with a guitar pick. Take this Christmas tree for example, which uses a 555 timer and a CB4017 decade counter in order to drive some blinking LEDs. The ICs are ...

Ever wanted a 555 timer with complementary non-overlapping outputs. The XTR651 from X-Rel Semiconductor is just such a thing. Very similar to the good old 555, it includes a built-in 200pF timing ...

Circuits employing the popular 555 timer circuits are often reliable under many conditions. When you use them in electrically noisy environments, however, the timer can produce a false trigger, no ...

He used a 555 timer that outputs a clock to the LEDs on the biz card, and placing a nine-volt battery on the terminals sets off the mini light show. See for yourself in the video below.

Used in a variety of timer, pulse generation, and oscillator applications, the 555 was designed in 1971 by Hans Camenzind. A favorite for many engineers, the 555 is still in widespread use due to its ...
