DESCRIPTION

The M54/74HC4020/HC4040 are high speed

CMOS 14/12-STAGE BINARY COUNTER

fabricated in silicon gate C²MOS technology. They

have the same high speed performance of LSTTL

combined with true CMOS low consumption.

The maximum division available at last stage is

1/16384 x f_INat clock.

For HC4040 each division stage has an output; the

final frequency is 1/4096 x f_IN.

All inputs are equipped with protection circuits

against static discharge and transient excess

voltage.

A clear input is used to reset the counter to the all

low level state.Ahighlevel on CLEAR accomplishes

the reset function. A negative transition on the

CLOCK input increments the counter by one.

For HC4020 twelve kind od divided output are

provided; 1st and 4th stage to 14th stage.
