The LMC555CMX/NOPB is a CMOS single timer and oscillator from Texas Instruments in an 8-pin SOIC package, specified to 3 MHz and operating from a 1.5 V to 15 V supply. It draws 50 uA quiescent current and can deliver 100 mA of output current, with 100 ns propagation and turn-on delay. A CMOS implementation of the 555 architecture keeps the classic three-resistor timing topology while cutting supply current by orders of magnitude relative to the bipolar original and extending operation down to low supply rails. Maximum power dissipation is 740 mW over a -40 C to 85 C range.

CMOS 555-type timers are used as free-running oscillators, monostable one-shots, pulse-width modulators, frequency dividers and simple sequencers, and they appear across industrial control boards, sensor excitation circuits, LED and backlight dimming, alarm and tone generation, and battery-powered consumer products. The low quiescent current makes the CMOS version viable in designs where the original bipolar 555 would dominate the standby budget. Buyers include industrial OEMs, prototyping and education channels, and repair operations sustaining legacy assemblies. The part is in Production status with an Active manufacturer lifecycle, is RoHS compliant and lead free, and ships on tape and reel in 2, 500-piece quantities.
