ICM7556IPD Datasheet PDF – CMOS RC Timer IC

The ICM7555 and ICM7556 are CMOS RC timers providing significantly improved performance over the standard SE555, NE555, NE556 and NE355 timers, while at the same time being direct replacements for those devices in most applications.

Part Number : ICM7556

Function: General-Purpose Timer IC

Package: DIP 14 Pin type

Manufacturer:  Analog Devices, Harris, Maxim-IC


ICM7556IPD datasheet pdf


ICM7556IPD is general-purpose RC timer IC. 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.
