ICM7555/ICM7556 General Description The Maxim ICM7555 and ICM7556 are respectively single and dual general-purpose RC timers capable of generating accurate time delays or frequencies. The primary feature is an extremely low supply current, making this device ideal for battery-powered systems. Additional features include low THRESHOLD, TRIGGER, and RESET currents, a wide operating supply voltage range, and improved performance at high frequencies. These CMOS low-power devices offer significant performance advantages over the standard 555 and 556 bipolar timers. Low-power consumption, combined with the virtually nonexistent current spike during output transitions, make these timers the optimal solution in many applications.
