Product details

CMOS 555 timer with 60 µA supply current

The ICM7555CBAZ-T is a CMOS version of the classic 555 timer from Renesas, dropping the supply current to 60 µA typical — a fraction of what a standard bipolar 555 draws. That 60 µA figure is the headline spec for any design where the timer runs continuously and the system battery life matters. It operates from 2V to 18V, so the same part can sit on a 3.3V MCU rail or a 12V industrial supply without a separate regulator. The 1MHz maximum frequency covers most PWM, delay, and oscillator needs below the RF band.

Pin-compatible drop-in for 8-SOIC footprints

The ICM7555CBAZ-T uses the standard 555 pinout in an 8-SOIC package (0.154" width, 3.90mm body). A board laid out for an NE555 or LMC555 in the same SOIC footprint will accept this part without a layout spin. The CMOS construction eliminates the bipolar 555's shoot-through current spike during output transitions, which reduces supply noise and lets the output swing rail-to-rail. For a precision timing application, the lower supply sensitivity means the period drifts less with supply ripple.

Active production, ROHS3 compliant, tape-and-reel ready

Renesas lists the ICM7555CBAZ-T as Active, so there is no near-term obsolescence risk for a production BOM. The 8-SOIC package is a common footprint with wide second-source availability if a supply constraint ever appears.

Frequently asked questions

Is ICM7555CBAZ-T a direct replacement for a standard NE555 timer?

Yes, the ICM7555CBAZ-T is pin-compatible with the standard 555 timer in the same 8-SOIC footprint. The key difference is the CMOS output stage: it draws 60 µA supply current versus several mA for a bipolar NE555, and its output swings rail-to-rail. For most astable and monostable circuits, it is a drop-in replacement. Verify the output drive current and timing resistor values against your load — the CMOS output has higher on-resistance than a bipolar 555.
