DESCRIPTION The M54HC4020 is an high speed CMOS 14 STAGE BINARY COUNTER fabricated with silicon gate C2MOS technology.

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 M54HC4020 twelve kind of 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. All inputs are equipped with protection circuits against static discharge and transient excess voltage.
