M74HC4060 14-stage binary counter/oscillator
The M74HC4060 device is a high speed CMOS 14-stage binary counter/oscillator fabricated with silicon gate C2MOS 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 of the oscillator frequency.
The I input and the CLEAR input are equipped with protection circuits against static discharge and transient excess voltage.
