IN74HC4060A
14 STAGE BINARY
COUNTER/OSCILLATOR
The IN74HC4060A is an high speed CMOS 14-STAGE BINARY
COUNTER/OSCILLATOR fabricated with silicon gate C
2
MOS
technology. The oscillator configuration allows design of either RC or
crystal oscillator circuits. A high level on the CLEAR accomplishes the
reset function, i.e. all counter outputs are made low and the oscillator is
disabled.
A negative transition on the clock input increments the counter. Ten kinds
of divided output are provided; 4 to 10 and 12 to 14 stage inclusive. The
maximum division available at Q12 is 1/16384 f oscillator.
The Clock Input (
∅I
) and the CLEAR input are equipped with protection
circuits against static discharge and transient excess voltage.
