Pin-for-pin compatible with 555 series of timers and 8-pin mdip package
The Lmc555 is a CMOS version of the industry standard 555 Series general purpose timers. Available in standard packages soic, msop, and dip. 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 National semiconductor's lmcmos process extends both the frequency range and low supply capability.
