LMC555
CMOS Timer
General Description
The LMC555 is a CMOS version of the industry standard
555 series general purpose timers. It offers the same capa-
bility 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 pre-
cisely 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 capaci-
tor. The use of National Semiconductor’s LMCMOS
pro-
cess extends both the frequency range and low supply capa-
bility.
