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

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 monostable circuit operation is almost identical to the astable oscillator, however the trigger input is not connected to the timing capacitor.

Adding the long-first-pulse malady in less traditional 555 astable topologies including CMOS- and bipolar-based oscillators that generate 50:50 symmetrical square waves. A previous Design Idea, “ ...

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 ...
