General Description
The LMC555 is a CMOS version of the industry standard 555 series general purpose timers. In addition to the
standard package (SOIC, MSOP, and MDIP) the LMC555 is also available in a chip sized package (8 Bump
micro SMD) using National's micro SMD package technology. 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 a 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 National Semiconductor's LMCMOS process extends
both the frequency range and low supply capability.
