The NE555 is a highly stable controller capable of producing accurate time delays or oscillation. It has low turn-off time, maximum operating frequency greater than 500kHz, timing from microseconds to hours, operates in both astable and monostable modes, high output current can source or sink 200mA, adjustable duty cycle, TTL compatible, and temperature stability of 0.005% per °C.
The NE555 family (NE555, SA555, SE555) are general‑purpose single bipolar timers available in a plastic DIP‑8 package. They operate in astable or monostable modes, support timing from microseconds to hours, and can source or sink up to 200 mA output current.
