DESCRIPTION
The M54/74HC4060 is a high speed CMOS 14-
STAGE BINARY COUNTER/OSCILLATOR fabri-
cated in silicon gate C2MOS technology. 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 pro-
vided ; 4 to 10 and 12 to 14 stage inclusive. The
maximum division available at Q12 is 1/16384 f os-
cillator.
The Ø1 input and the CLEAR input are equipped
with protection circuits against static discharge and
transient excess voltage.

Note : When CR or crystal oscillation circuit is adopted, the dynamic power dissipation will be greater than the measured value from the test
circuit shown left, because these oscillion circuits spend much supply current.
