Stresses above those listed under ”Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating only

and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification

is not implied. Exposure to absolute maximum rating conditions for external periods may affect device reliability.

JAM inputs is asynchronously forced into the

counter regardless of the state of the SPE, CI/CE,

or CLOCK inputs. JAM inputs JO-J7 represent two

4-bit BCD words for the HCC/HCF40102B and a

single 8-bit binary word for the HCC/HCF40103B.

When the CLEAR (CLR) input is low, the counter

is asynchronously cleared to its maximum count

theHCC/HCF40103B) regardless of the state of

any other input. The precedence relationship be-

tween control input is indicated in the truth table. If

all control inputs are high at the tieme of zero count,

the counters will jump to the maximum count, giving

a counting sequence of 100 or 256 clock pulses

long. The HCC/HCF40102B and HCC/HCF40103B

may be cascaded using the CI/CE input and the
