LMC555
CMOS Timer
General Description
The LMC555 is a CMOS version of the industry standard
555 series general purpose timers. In addition to the stan-
dard 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 of-
fers 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 oscil-
lation frequency and duty cycle are accurately set by two ex-
ternal resistors and one capacitor. The use of National Semi-
conductor’s LMCMOS
process extends both the frequency
range and low supply capability.
