The LMC555 device is a CMOS version of the industry standard 555 series general-purpose timers. In addition to the standard package (SOIC, VSSSOP, and PDIP) the LMC555 is also available in a chip-sized package (8-bump DSBGA) using TI's DSBGA 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 oscillation frequency and duty cycle are accurately set by two external resistors and one capacitor. The use of TI's LMCMOS process extends both the frequency range and the low supply capability.
