The LMC555 is a CMOS version of the industry standard 555 series general purpose timers.
The LMC555 is a CMOS version of the industry-standard 555 series general-purpose timer, offering the same capabilities for generating accurate time delays and frequencies as the LM555 but with significantly lower power dissipation and supply current spikes. It is available in standard packages (SOIC, MSOP, MDIP) as well as a chip-sized 8-Bump micro SMD package using National Semiconductor's micro SMD technology.
