IKSEMICON ILC556DT

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.

* Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device.
These are stress ratings only and functional operation of the device at these or any other conditions beyond those
indicated under “recommended operating conditions” is not implied.
Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
