The 555 timer does “one thing” — compares a voltage ... The LEDs blink with 555s, and the board looks snazzy. Finally, our judges really liked CS 555, a wholly circuit-sculpture discrete ...

then ultimately ended up building the three main logic blocks inside the familiar timer on pieces of copper-clad board. He’d built a 555 using discrete components. While this isn’t 100% ...

I agree with Pease, and have always regarded the 555 timer as more of a hobbyist IC ... you get problems with stray capacitance on the board. It becomes a proximity sensor that changes frequency ...

Such was the case for one student, who had the canny idea to make a card that demonstrates his printed circuit board know-how. He used a 555 timer that outputs a clock to the LEDs on the biz card ...

Figure 1 The 555 timer test circuit is configured for a low duty cycle. The circuit was built and tested on bread board. It worked well and the customer was pleased, but the academic in me, as well as ...

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 ...

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 ...

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 ...
