In the classic configuration and most variants of the astable 555 multivibrator circuit, the timing characteristics are based on the charging and discharging of a capacitor. However, it can be argued ...

Astable Multivibrator Market Scope: Astable multivibrator, also known as free-running multivibrator, oscillates between two states, continually producing two square wave output waveforms.

Figure 3 The long first-pulse problem also occurs in a 50:50 square wave topology popular for CMOS 555s. Happily, the same fix from “ Gated 555 astable hits the ground running ” works in this genre of ...

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 ...

Luckily, [Ray] published an illustrated guide on building multivibrator circuits. This is a simple method of assembling a two-output oscillator.

Fig 2. U1a, connected as an astable multivibrator, outputs a sawtooth-like waveform across C1 (VC1). U1b compares VC1 to a reference voltage (VRef) provided by U3.
