APPLICATIONS
Conversion of Clock up, Clock Down Input Sig-
nals to Clock and Up/Down Inputs Signals.
Cascading Counter Packages.
The
HCC/HCF4029B
CLOCK and UP/DOWN in-
puts are used directly inmost applications. In appli-
cations where CLOCK UP and CLOCK DOWN
inputs
are
provided,
HCC/HCF4029B
CLOCK and UP/DOWN inputs
can easilybe realized by use of the circuit.
HCC/HCF4029B
changes count on positive transi-
tions of CLOCK UP or CLOCK DOWN inputs. For
the gateconfiguration shown below, when counting
up the CLOCK DOWN input must be maintained
high and conversely when counting down the
CLOCKUP input must be maintained high.

operation. However,if the CARRY-OUTsignals
are used to trigger otheredge-sensitive logicdevices, suchasFF’sor counters, theCARRY-OUTsignals shouldbe gated withtheclocksignal
using a 2-input NOR gate suchas

RippleClocking Mode: The Up/Down controlcan be changed at any count. Theonlyrestriction on changing the Up/Down control is thatthe
clock inputto the firstcounting stage must behigh.
