It has the same high speed performance of LSTTL combined with true CMOS low power consumption. It operates ten times faster than metal-gate C2MOS IC (4060B) with the same power dissipation. 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 1 input and the CLEAR input are equipped with protection circuits against static discharge and transient excess voltage. M……
