    DATASHEET General Purpose Timers
    ICM7555, ICM7556 Features The ICM7555 and ICM7556 are CMOS RC timers providing
    significantly improved performance over the standard
    SE/NE 555/556 and 355 timers, while at the same time being
    direct replacements for those devices in most applications.
    Improved parameters include low supply current, wide
    operating supply voltage range, low Threshold, Trigger and
    Reset currents, no crowbarring of the supply current during
    output transitions, higher frequency performance and no
    requirement to decouple Control Voltage for stable operation. Exact equivalent in most cases for SE/NE 555/556 or
    TLC555/556 Specifically, the ICM7555 and ICM7556 are stable controllers
    capable of producing accurate time delays or frequencies. The
    ICM7556 is a dual ICM7555, with the two timers operating
    independently of each other, sharing only V+ and GND. In the
    one shot mode, the pulse width of each circuit is precisely
    controlled by one external resistor and capacitor. For astable
    operation as an oscillator, the free running frequency and the
    duty cycle are both accurately controlled by two external
    resistors and one capacitor. Unlike the regular bipolar
    SE/NE 555/556 devices, the Control Voltage terminal need not
    be decoupled with a capacitor. The circuits are triggered and
    reset on falling (negative) waveforms, and the output inverter
    can source or sink currents large enough to drive TTL loads, or ...
