FEATURES DESCRIPTION 2 The LM555 is a highly stable device for generating • Direct Replacement for SE555/NE555 accurate time delays or oscillation. Additional • Timing from Microseconds through Hours terminals are provided for triggering or resetting if • Operates in Both Astable and Monostable desired. In the time delay mode of operation, the time Modes is precisely controlled by one external resistor and capacitor. For astable operation as an oscillator, the • Adjustable Duty Cycle free running frequency and duty cycle are accurately • Output Can Source or Sink 200 mA controlled with two external resistors and one • Output and Supply TTL Compatible capacitor. The circuit may be triggered and reset on • Temperature Stability Better than 0.005% per falling waveforms, and the output circuit can source or sink up to 200mA or drive TTL circuits. °C • Normally On and Normally Off Output • Available in 8-pin VSSOP Package APPLICATIONS • Precision Timing • Pulse Generation • Sequential Timing • Time Delay Generation • Pulse Width Modulation • Pulse Position Modulation • Linear Ramp Generator
