||NE555 SA555 - SE555
General-purpose single bipolar timers
■ Low turn-off time ■ Maximum operating frequency greater than
500 kHz ■ Timing from microseconds to hours ■ Operates in both astable and monostable
modes ■ Output can source or sink up to 200 mA ■ Adjustable duty cycle ■ TTL compatible ■ Temperature stability of 0.005% per °C
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 .
