DESCRIPTION The NE555 is a highly stable controller capable of producing accurate timing pulse.With monostable operation,the time delay is controlled by one extermal and one capacitor.With a stable operation,the frequency and duty cycle are accurately controlled with two external resistors and one capacitor. FEATURES High current driver capability(=20mA) Adjustable duty cycle Temperature stability of 0.005%/℃ Timing from μSec to Hours Turn off time less than 2μSec APPLICATION Precision timing Pulse generation Timing delay generation Sequential timing
