LMC555CMM

TEXAS INSTRUMENTS  LMC555CMM  芯片, CMOS 定时器

The is a CMOS version industry standard 555-series General-purpose Timer 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 "s LMCMOS process extends both the frequency range and the low supply capability.
