PIN DESCRIPTIONS
INPUTS
Clock (Pin 10)
Negative–edge triggering clock input. A high–to–low tran-
sition on this input advances the state of the counter.
Reset (Pin 11)
Active–high reset. A high level applied to this input asynch-
ronously resets the counter to its zero state, thus forcing all Q
outputs low.
OUTPUTS
Q1 thru Q12 (Pins 9, 7, 6, 5, 3, 2, 4, 13, 12, 14, 15, 1)
Active–high outputs. Each Qn output divides the Clock
input frequency by 2N.
