NE556D Datasheet (ST Microelectronics) - General-purpose dual bipolar timer

NE556D, General-purpose dual bipolar timer

The NE556, SA556 and SE556 dual monolithic timing circuits are highly stable controllers capable of producing accurate time delays or oscillation.

In the time delay mode of operation, the time is precisely controlled by one external resistor and capacitor.

For a stable operation as an oscillator, th
