The LM555 is a low-power, high-performance single-chip timer circuit introduced by Fairchild Semiconductor. It is mainly used to construct various multivibrators, one-shot triggers, delay circuits and pulse generators. The LM555 has a wide operating voltage range, high frequency accuracy, high oscillation stability, and high reliability, which is widely used in various electronic products.
The LM555/NE555/SA555 is a highly stable single‑timer controller with high current drive capability (200 mA) and adjustable duty‑cycle operation. It can be used for precision timing, pulse generation, time‑delay generation and sequential timing applications.
The document provides absolute maximum ratings, electrical characteristics, typical application circuits (monostable, astable, frequency divider, PWM, PPM) and ordering information for the 8‑DIP and 8‑SOP packages.
