世界一流的小尺寸 555 定时器，同时拥有低功耗，高精度和最大频率为 3MHz（军用版）的特性
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 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 astable mode the oscillation frequency and duty cycle are accurately set by two external resistors and one capacitor. The use of TIs LMCMOS process extends both the frequency range and the low supply capability.
