The HCC4521B and HCF4521B are monolithic in-
tegrated circuits, available in 16-lead dual-in-line
plasticorceramic packages and plasticmicro pack-
ages.
The HCC4521B and HCF4521B have a chain of 24
flip-flopswithan inputcircuitthatallowsthreemodes
of operation. The input circuit functions as a crystal
or an RC oscillator or as an input buffer for an ex-
ternaloscillator. Each flip-flop preforms a divide-by-
two function giving a total count of 2
24
= 16, 777,
216. The count advances on the negative going
edge of the clock. Access is available to the final
seven stages giving the device added flexibility.
