Philips Semiconductors Linear Products Product specification Timer NE/SA/SE555/SE555C DESCRIPTION PIN CONFIGURATIONS The 555 monolithic timing circuit is a highly stable controller capable D, N, FE Packagesof 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 GND 1 8 VCC free running frequency and the duty cycle are both accurately TRIGGER 2 7 DISCHARGE controlled with two external resistors and one capacitor. The circuit may be triggered and reset on falling waveforms, and the output OUTPUT 3 6 THRESHOLD structure can source or sink up to 200mA. RESET 4 5 CONTROL VOLTAGE FEATURES F Package • Turn-off time less than 2µs GND 1 14 VCC • Max. operating frequency greater than 500kHz NC 2 13 NC • Timing from microseconds to hours TRIGGER 3 12 DISCHARGE OUTPUT 4 11 NC• Operates in both astable and monostable modes • High output current NC 5 10 THRESHOLD RESET 6 9 NC • Adjustable duty cycle NC 7 8 CONTROL VOLTAGE • TTL compatible • Temperature stability of 0.005% per °C TOP VIEW APPLICATIONS • Precision timing • Pulse generation •…
