INTEGRATED CIRCUITS NE/SA/SE555/SE555C Timer Product data Supersedes data of 1994 Aug 31 Philips Semiconductors 2003 Feb 14 Philips Semiconductors Timer Product data NE/SA/SE555/SE555C DESCRIPTION The 555 monolithic timing circuit is a highly stable controller 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 • Turn-off time less than 2 µs • Max. operating frequency greater than 500 kHz • Timing from microseconds to hours • Operates in both astable and monostable modes • High output current • Adjustable duty cycle • TTL compatible • Temperature stability of 0.005% per °C APPLICATIONS • Precision timing • Pulse generation • Sequential timing • Time delay generation • Pulse width modulation PIN CONFIGURATION D and N Packages GND 1 TRIGGER 2 OUTPUT 3 RESET 4 8 VCC 7 DISCHARGE 6 THRESHOLD 5 CONTROL VOLTAGE SL00349 Figure 1.
