1 Features 3 Description
1 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 Modes desired. In the time delay mode of operation, the time
• Adjustable Duty Cycle is precisely controlled by one external resistor and
capacitor. For a stable operation as an oscillator, the
• Output Can Source or Sink 200 mA free running frequency and duty cycle are accurately
• Output and Supply TTL Compatible controlled with two external resistors and one
• Temperature Stability Better than 0.005% per °C capacitor. The circuit may be triggered and reset on
falling waveforms, and the output circuit can source • Normally On and Normally Off Output
or sink up to 200 mA or drive TTL circuits.
• Available in 8-pin VSSOP Package
