ICM7555/ ICM7556 General Description The Maxim ICM7555 and ICM7556 are respectively si ngle and dual general-purpose RC timers capable of generating accurate time de lays or frequencies.
The primary featur e is an extremely low supply current, m aking this device ideal for battery-pow ered systems.
Additional features inclu de low THRESHOLD, TRIGGER, and RESET cu rrents, a wide operating supply voltage range, and improved performance at hig h frequencies.

General Purpose Timers
The ICM7555 and ICM7556 are CMOS RC tim ers providing significantly improved pe rformance over the standard SE/NE 555/5 56 and 355 timers, while at the same ti me being direct replacements for those devices in most applications.
Improved parameters include low supply current, wide operating supply voltage range, lo w Threshold, Trigger and Reset currents , no crowbarring of the supply current during output transitions, higher frequ ency performance and no requirement to decouple Control Voltage for stable ope ration.
Specifically, the ICM7555 and I CM7556 are sta .
