description/ordering information (continued)
The outputs of the four flip-flops are triggered on a low-to-high-level transition of either count (clock) input (UP
or DOWN). The direction of counting is determined by which count input is pulsed while the other count input
is high.
All four counters are fully programmable; that is, each output may be preset to either level by placing a low on
the load (LOAD) input and entering the desired data at the data inputs. The output changes to agree with the
data inputs independently of the count pulses. This feature allows the counters to be used as modulo-N dividers
simply by modifying the count length with the preset inputs.
A clear (CLR) input has been provided that forces all outputs to the low level when a high level is applied. The
clear function is independent of the count and LOAD inputs.
These counters were designed to be cascaded without the need for external circuitry. The borrow (BO) output
produces a low-level pulse while the count is zero (all outputs low) and DOWN is low. Similarly, the carry (CO)
output produces a low-level pulse while the count is maximum (9 or 15), and UP is low. The counters then can
be cascaded easily by feeding BO and CO to DOWN and UP, respectively, of the succeeding counter.
