KODENSHI KKC556N

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.
