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-stage synchronous

down counter with a single output which is active when

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 inputs for 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 transition regardless of the state of the

CI/CE

input.

When

the

ASYNCHRONOUS

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