Product Summary

The MC74HC4020ADR2G is identical in pinout to the standard CMOS MC14020B. The MC74HC4020ADR2G inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs. The MC74HC4020ADR2G consists of 14 master−slave flip−flops with 12 stages brought out to pins. The output of each flip−flop feeds the next and the frequency at each output is half of that of the preceding one. Reset is asynchronous and active−high.
