DESCRIPTION
The LMC555 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 Texas Instruments' LMCMOS
process extends both the frequency range and low
supply capability.
