TECHNICAL DATA

General purpose dual timer

KKC556N

KKC556N/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.
