LMC555 CMOS Timer

Check for Samples: LMC555

FEATURES

DESCRIPTION

•

Less than 1 mW Typical Power Dissipation at

5V Supply

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.

•
