Description
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
capacitor. For a stable operation as an oscillator,
the free running frequency and the duty cycle are
both accurately controlled with two external
resistors and one capacitor.
The circuit may be triggered and reset on falling
waveforms, and the output structure can source
or sink up to 200 mA.
Features
1. Low turn-off time
2. Maximum operating frequency greater than 500 kHz
3. Timing from microseconds to hours
4. Operates in both astable and monostable modes
5. Output can source or sink up to 200 mA
6. Adjustable duty cycle
7. TTL compatible
8. Temperature stability of 0.005% per °C
