Product Overview

The LM555CMM/NOPB is a Highly Stable Timer for generating accurate time delays and oscillation. Additional terminals are provided for triggering or resetting if desired. In the time delay mode of operation, the time is precisely controlled by one external resistor and capacitor. For astable operation as an oscillator, the free running frequency and duty cycle are accurately controlled with two external resistors and one capacitor. The circuit may be triggered and reset on falling waveforms and the output circuit can source or sink up to 200mA or drive TTL circuits.
  • Direct replacement for SE555/NE555
  • Timing from microseconds through hours
  • Operates in both astable and monostable modes
  • Adjustable duty cycle
  • Output can source or sink 200mA
  • Output and supply TTL-compatible
  • Normally ON and normally OFF output
  • Green product and no Sb/Br


Clock & Timing


Device has limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
