DESCRIPTION
The HCC40102B, HCC40103B, (extended tempera-
ture range) and the HCF40102B, HCF40103B (inter-
mediate temperature range) are monolithic integrated
circuits, available in 16-lead dual in-line plastic or ce-
ramic package. The HCC/HCF40102B, and
HCC/HCF40103B consist of an 8-stagesynchronous
down counterwith asingle output whichisactivewhen
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 type has control inputsfor enabling or
disabling the clock, for clearing the counter to its
maximum count, and for presetting the counter
either synchronously 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 each posi-
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
positive clock transitionregardless of the state of the
CI/CE input. When the ASYNCHRONOUS
PRESET-ENABLE (APE) input is low, data at the
