Product details

Runs on a 4.5 V to 16 V supply rail and draws a typical 10 mA. The 0°C to 70°C temperature grade covers most indoor and commercial equipment, but not extended industrial or automotive ambient — if the board lives in a hot enclosure or engine bay, the LM555CMM/NOPB is outside its rated window.

Package and footprint — 8-VSSOP versus the classic DIP

The 8-VSSOP body measures 3.00 mm wide, which is roughly half the width of the standard SOIC-8. The 0.65 mm pin pitch and small footprint save board space but demand a finer soldering profile — a rework station with a fine-tip nozzle and a hot-air profile below 260°C peak keeps the plastic body distortion-free. The supplier device package is 8-VSSOP, so the PCB land pattern matches that specific outline, not the wider MSOP-8 variant.

Frequently asked questions

What is the closest pin-compatible alternative to the LM555CMM/NOPB?

The LM555CMM/NOPB is a TI-specific order code for the 555 timer in the 8-VSSOP package; other 555-type timers in the same package from other brands may be functional equivalents, but pin compatibility and timing characteristics should be verified against the target datasheet.
