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.
* All voltages are with respect to V
SS
(GND).
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
(99
10
for the HCC/HCF40102B and 255
10
for
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. TheHCC/HCF40102B and HCC/HCF40103B
may be cascaded using the CI/CE input and the
