Reliable 555 timer doesn’t falsely trigger Powering the timer from a NOR gate keeps it unpowered until needed. Power an LED driver using off-the-shelf components Drive LEDs with a 555 timer and two ...

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… ...

In this mode of operation, the timer functions as a one-shot. The circuit operates in the following manner. A short pulse (> 1.2V) applied to point I/P energizes transistor Q 1, pulling the 9V battery ...

You asked for it, and now you’ve got it. It’s taken more than a decade of accumulated complaining, but this gigantic 555 timer IC has finally gathered enough psychokinetic energy to tak… ...

Back in 2011, Jeff Hamilton contacted Bob Pease, asking for Bob’s experience with the classic 555 timer IC.Jeff wrote Pease, “As part of celebrating a part with 40 years in the market, I ...

The bipolar NE555 timer IC is widely used in inductorless dc-dc converters, most frequently in doubling and inverting converters. However, another very popular IC, the LM386 audio ...

The 555 timer IC is an integrated circuit (chip) which is used in a variety of timer, delay, pulse generation, and oscillator applications. 555 Signals and Pinout (8 pin DIP) Figure below shows ...
