It oscillates up to 500 kHz and runs from a 2V to 16.5V supply, so it fits both 3.3V portable gear and legacy 12V industrial panels. The -40°C to 85°C operating range covers outdoor telecom, factory automation, and engine-bay-adjacent electronics without needing an automotive-grade part. ## 30 µA supply — what it means for the BOM The 30 µA quiescent current is the headline spec that separates this part from a standard 555. In a battery-powered timer or watchdog circuit, that difference can extend standby life from weeks to years on a coin cell. The 500 kHz maximum frequency is adequate for PWM dimming, tone generation, and one-shot delays up to several seconds; for higher-speed clocking you would step to a dedicated oscillator. ## Active production, no obsolescence risk The ICM7555ESA+T carries an Active product status and ROHS3 compliance. ## Pin-compatible with the standard 555 footprint The ICM7555ESA+T is housed in an 8-SOIC package (3.90 mm body width) and is a drop-in replacement for any 8-pin 555-type timer on the same footprint. The CMOS output swings rail-to-rail, so it drives CMOS logic inputs directly without a pull-up resistor.","metaTitle":"ICM7555ESA+T 555 Timer, 500kHz, 2V-16.5V, 8-SOIC","metaDescription":"Maxim ICM7555ESA+T low-power 555 timer/oscillator. 30 µA supply, 500 kHz max, 2V-16.5V range, -40°C to 85°C.
