SNAS558M – FEBRUARY 2000 – REVISED JULY 2016 LMC555 CMOS Timer
1 Features 3 Description •
• 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 chipsized 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
astable 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. 1 • …
