PIN DESCRIPTIONS
INPUTS
Osc In (Pin 11)
Negativeedge triggering clock input. A hightolow
transition on this input advances the state of the counter. Osc
In may be driven by an external clock source.
Reset (Pin 12)
Activehigh reset. A high level applied to this input
asynchronously resets the counter to its zero state (forcing
all Q outputs low) and disables the oscillator.
OUTPUTS
Q4—Q10, Q12Q14 (Pins 7, 5, 4, 6, 13, 15, 1, 2, 3)
Activehigh outputs. Each Qn output divides the Clock
input frequency by 2N. The user should note the Q1, Q2, Q3
and Q11 are not available as outputs.
Osc Out 1, Osc Out 2 (Pins 9, 10)
Oscillator outputs. These pins are used in conjunction
with Osc In and the external components to form an
oscillator. When Osc In is being driven with an external
clock source, Osc Out 1 and Osc Out 2 must be left open
circuited. With the crystal oscillator configuration in Figure
6, Osc Out 2 must be left open circuited.
