Description

The NE555 is arguably the most iconic integrated circuit ever designed. Introduced by Signetics in 1972, it has sold over a billion units and remains in production today. This versatile 8-pin timer can operate in monostable (one-shot), astable (oscillator), or bistable (flip-flop) modes. Applications span from simple LED flashers to precision timing circuits, PWM controllers, and tone generators. The D suffix indicates the SOIC-8 surface-mount package.
