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
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 oscil-
lation 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 fre-
quency range and low supply capability.
