The ICM7555CBAZ is a CMOS version of the classic 555 timer, built by Renesas. It delivers the same astable and monostable timing functions as the bipolar NE555, but draws only 60 µA typical supply current — a fraction of the bipolar part's quiescent draw. The 1 MHz maximum frequency covers audio-range PWM, tone generation, and moderate-speed pulse trains.

Product details
Frequently asked questions
Is ICM7555CBAZ a direct replacement for the bipolar NE555?
Pin-compatible in the same 8-pin DIP/SOIC footprint, yes — the same astable and monostable circuits work. The key difference is supply current: the ICM7555CBAZ draws 60 µA typical versus several milliamps for the NE555. The output drive current is also lower on the CMOS version, so check the load before swapping. For most low-power timing and PWM applications it is a drop-in improvement.
What supply voltage does ICM7555CBAZ operate at?
Rated for 2V to 18V. That covers single-cell Li-ion (3.6V), 5V logic rails, 12V industrial supplies, and 15V analog rails. No external regulator needed across that range.
