SE555 timer equivalent, general-purpose single 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 NE555, SA555, and SE555 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 capacito.
