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 ...

The popular Timer IC 555 is extensively used in short duration timing applications. IC 555 is a highly stable integrated circuit functioning as an accurate time delay generator and free running ...

The synth relies on two 555 timer ICs as the oscillators and an LM741 op-amp. These parts harken right back to the dawn of the integrated circuit era, and still do a great job in this application.

But it gets the job done with a readily available IC and no need to code for a microcontroller. The original idea came from a solar battery charger entered in the 555 timer contest.

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 ...

The 555 timer IC has been reinvented—again. Signetics introduced the enormously popular chip back in 1971, and it quickly became a big hit. Myriad application circuits have used it throughout ...

In these applications, a 555 timer can replace the microprocessor and still allow accurate control of LED current independently of input voltage, temperature, and LED forward-voltage drops. IC 2 , a ...

This voltage-booster circuit for driving one or more white LEDs uses a 555 timer as its main element (see the figure). The timer, IC1, functions as a resettable astable multivibrator ...
