Product Overview

The LMC555CN/NOPB is a CMOS Timer with low power and high performance to generate accurate time delays. The LMC555 offers the same capability of generating accurate time delays and frequencies as the LM555 but with much lower power dissipation and supply current spikes. When operated as an one-shot, the time delay is precisely controlled by a single external resistor and capacitor. In the stable mode the oscillation frequency and duty cycle are accurately set by two external resistors and one capacitor. The use of TI's LMCMOS process extends both the frequency range and the low supply capability.
  • <1mW Typical power dissipation at 5V supply
  • 3MHz Astable frequency capability
  • Output fully compatible with TTL and CMOS logic at 5V supply
  • Reduced supply current spikes during output transitions
  • Extremely low reset, trigger and threshold currents
  • Excellent temperature stability
  • Pin-for-pin compatible with 555 series of timers
  • Green product and no Sb/Br


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.
