Product details

CMOS 555 timer in an 8-DIP socket

The ICM7555IPAZ is a single CMOS 555-type timer/oscillator from Renesas, rated for 1 MHz maximum oscillation and drawing just 60 µA supply current at 2 V. That supply current is the headline difference from a standard bipolar 555 — on a battery-powered board or a thermally tight enclosure, the CMOS version keeps the heat and the drain low while dropping into the same 8-pin DIP footprint.

The part operates from 2 V to 18 V, covering 3.3 V, 5 V, 12 V, and 15 V rails without an external regulator. The -25°C to 85°C temperature range suits industrial control panels, outdoor telecom cabinets, and factory-floor sensor interfaces — the same environments where a failed bipolar 555 often scorches the board.

Active lifecycle, through-hole package

The 8-DIP (0.300", 7.62 mm) through-hole package is a standard socketed form factor — no board redesign needed if you are replacing a failed 555 timer in legacy equipment. The supplier device package is 8-PDIP.

Frequently asked questions

Is the ICM7555IPAZ a direct drop-in replacement for a standard bipolar 555 timer in an 8-DIP socket?

Yes — the ICM7555IPAZ uses the same 8-DIP (0.300", 7.62 mm) footprint and standard 555 pinout. The key difference is supply current: 60 µA typical versus 3–10 mA for a bipolar 555. On a board where the original bipolar timer failed due to heat or supply sag, the CMOS version often runs cooler and extends system life. Confirm the supply voltage is within 2 V to 18 V and that the 1 MHz max frequency meets your timing requirements.

What is the best equivalent for ICM7555IPAZ from other brands?

Pin-compatible CMOS 555 timers in 8-DIP include the Texas Instruments TLC555 and the Microchip (formerly Atmel) ICM7555 — both share the same low-power CMOS architecture and 2 V to 18 V supply range. Verify the specific temperature grade and package marking against your BOM before committing.
