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.
A clear input is used to reset the counter to the all
low level state. A high level 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.
The maximum division available at last stage is
1/16384 x fIN at clock.
For HC4040 each division stage has an output; the
final frequency is 1/4096 x fIN.
All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.

(*) CPD is defined as the value of the IC’s internal equivalent capacitance which is calculated from the operating current consumption without load.
(Refer to Test Circuit). Average operting current can be obtained by the following equation. ICC(opr) = CPD •VCC •fIN + ICC/2 (per FLIP/FLOP)
