TECHNICAL DATA ILC556N General Purpose Dual Timer ILC556N/D is designed to be used: as high-precision pulse oscillator with adjustable frequency and on-off time ratio; for producing accurate time delays using external resistors and capacitors; as a timer in domestic appliances, in measuring equipment, computers; as functional units in electronic instruments. The timer may be used as oscillator producing accurate time delays and frequencies. In astable mode the pulse width of each circuit is controlled by one external resistor and capacitor. In monostable mode, when used as oscillator, its own frequency of oscillation and on-off time ratio are controlled by two external resistors and one capacitor. Unlike bipolar timer, CONTROL VOLTAGE output does not require any capacitor decoupling. TRIGGER, RESET inputs are active as per low level. Output inverter provides sufficient drain and source currents to control TTL-loads, and provides minimum bias when controlling CMOS-loads. Input voltage levels are compatible with standard CMOS levels.
