SA556D timer equivalent, general-purpose dual bipolar timer.
* Low turn-off time
* Maximum operating frequency greater than
500 kHz
* Timing from microseconds to hours
* Operates in both astable and monostable
modes.
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 capa.
