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 ...

An astable 555 multivibrator circuit, where the timing characteristics are determined by the interplay of an inductor, resistor, and diode.

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 ...

Understanding DIL integrated circuits involves knowing their function and identifying pin one. The 555 timer IC produces astable and monostable outputs, requiring waveform interpretation and basic ...

[FightCube] wrote in recommending a very helpful piece of circuit simulation software for those of you still constructing entries for the 555 design contest. LTSpiceIV, available from Linear Tech… ...

When it comes to the venerable 555 timer, Paul Rako agrees with Bob Pease—avoid using it if your application demands any kind of precision.

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, ...

No, the clock is very clearly intentionally designed to have two independent power supplies, a positive 1.5V and negative 1.5V, with one battery powering each.
