DESCRIPTION
TheHCC4029B (extended temperature range) and
HCF4029B (intermediate temperature range) are
monolithic integrated circuit, available in 16-lead
dual in-line plastic or ceramic package and plastic
micro package.The HCC/HCF4029B consistsof a
four-stage binary or BCD-decade up/downcounter
withprovisions forlook-aheadcarryin bothcounting
modes. The inputs consist of a single CLOCK,
CARRY-IN(CLOCK ENABLE), BINARY/DECADE,
UP/DOWN, PRESET ENABLE, and four individual
JAM signals. Q1, Q2, Q3, Q4 and a CARRY OUT
signalareprovided asoutputs. AhighPRESETENABLEsignal allowsinformationon theJAMINPUTS
to preset the counter to any state asynchronously
with the clock. A low on each JAM line, when the
PRESET-ENABLE signal ishigh,resetsthecounter
toitszerocount. Thecounterisadvancedonecount
at the positive transition of the clock when the
CARRY-INand PRESET ENABLE signals, arelow.
Advancement is inhibited when the CARRY-IN or
PRESET ENABLE signals are high. The CARRYOUT signal is normallyhigh and goes lowwhen the

counter reachesitsmaximumcount inthe UPmode
or the minimumcountinthe DOWN modeprovided
the CARRY-INsignal is low. The CARRY-IN signal
in the low state can thus be considered a CLOCK
ENABLE. The CARRY-IN terminal must be connectedtoVSSwhennot inuse.Binarycountingisaccomplished when the BINARY/DECADE input is
high ; thecounter counts in thedecade mode when
the BINARY/DECADE input is low. The counter
FUN CTIONAL DI AGR A M
counts Up when to UP/DOWN INPUT is high, and
Down when the UP/DOWN INPUT is low. Multiple
packages can be connected in either a parallelclockingor a ripple-clockingarrangement as shown
in cascading counter packages. Parallel clocking
provides synchronous control and hence faster response from all counting outputs. Ripple-clocking
allowsforlonger clock input rise and fall times.
