DESCRIPTION

The M54/74HC4020/HC4040 are high speed
CMOS 14/12-STAGE BINARY COUNTER
fabricated in silicon gate C2MOStechnology. They
have the same high speed performance of LSTTL
combined with true CMOSlow consumption.

A clear input is used to reset the counter to the all
lowlevelstate.Ahighlevelon CLEARaccomplishes
the reset function. A negative transition on the
CLOCKinput incrementsthe counterby one.

For HC4020 twelve kind od divided output are
provided; 1st and 4th stage to 14th stage.

The maximum division available at last stage is
1/16384 x fINatclock.

For HC4040 each division stage has an output; the
final frequency is 1/4096 xfIN.

All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.
