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

range and low supply capability.
