Product Summary

The LMC555CMX is a CMOS industry standard 555 general purpose timer. In addition to the standard package (SOIC, MSOP, and MDIP) the LMC555CMX is also available in a chip sized package (8 Bump micro SMD) using National’s micro SMD package technology. The LMC555CMX 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 of LMC555CMX is precisely controlled by a single external resistor and capacitor. In the stable mode the oscillation 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 frequency range and low supply capability.
