General DescriptionThe LMC555 is a CMOS version of the industry standard 555 series general purpose timers.
It offers the same capability of generating accurate time delays and frequencies 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
astable mode the oscillation frequency and duty cycle are accurately set by two external
resistors and one capacitor. The use of National Semiconductor's LMCMOS(TM) process
extends both the frequency range and low supply capability.
