PIN DESCRIPTIONS
INPUTS
Clock A (Pins 1, 15) and Clock B (Pins 4, 15)
Clock A is the clock input to the
÷
2 counter; Clock B is the
clock input to the
÷
5 counter. The internal flip–flops are
toggled by high–to–low transitions of the clock input.
CONTROL INPUTS
Reset (Pins 2, 14)
Asynchronous reset. A high at the Reset input prevents
counting, resets the internal flip–flops, and forces QA through
QD low.
OUTPUTS
QA (Pins 3, 13)
Output of the
÷
2 counter.
QB, QC, QD (Pins 5, 6, 7, 9, 10, 11)
Outputs of the
÷
5 counter. QD is the most significant bit.
QA is the least significant bit when the counter is connected
for BCD output as in Figure 4. QB is the least significant bit
when the counter is operating in the bi–quinary mode as in
Figure 5.
