CMOS
14/12-STAGE
fabricated in silicon gate C

MOS technology. 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.AhighlevelonCLEARaccomplishes
the reset function. A negative transition on the
CLOCKinput increments the counter by one.
For HC4020 twelve kind od divided output are
provided; 1st and 4th stage to 14th stage.

For HC4040each division stage has an output; the

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