,
HCC40103B
,(extended tempera-
turerange) and the
HCF40102B
,
HCF40103B
(inter-
mediate temperature range) aremonolithic integrated
circuits,available in 16-lead dual in-line plastic orce-
ramic
package.
The
HCC/HCF40103B
consistofan 8-stagesynchronous
downcounterwithasingleoutputwhichisactivewhen
the internal count is zero. The
HCC/HCF40102B
is
configured as two cascaded 4-bit BCD counters, and
the
HCC/HCF40103B
contains a single 8-bit binary
counter. Each typehas controlinputsforenabling or
disabling the clock, for clearing the counter to its
maximum count, and for presetting the counter
eithersynchronously or asynchronously. All control
inputs and the CARRY-OUT/ZERO-DETECT out-
put are active-low logic. In normal operation, the
counter is decremented by one count on eachposi-
tive transition of the CLOCK. Counting is inhibited
when the CARRY-IN/COUNTER ENABLE (CI/CE)
input is high. The CARRY-OUT/ZERO-DETEC
(CO/ZD) output goes low when the count reaches
zero if the CI/CE input is low, and remains low for
one full clock period. When the SYNCHRONOUS
PRESET-ENABLE (SPE) input is low, data at the
JAM input is clocked into the counter on the next
positiveclocktransitionregardless ofthestateofthe
CI/CE
input.

PRESET-ENABLE (APE) input is low, data at the
