CD4024BC 7-Stage Ripple Carry Binary Counter
October 1987
Revised April 2002
CD4024BC
7-Stage Ripple Carry Binary Counter
General Description
The CD4024BC is a 7-stage ripple-carry binary counter.
Buffered outputs are externally available from stages 1
through 7. The counter is reset to its logical “0” stage by a
logical “1” on the reset input. The counter is advanced one
count on the negative transition of each clock pulse.

Note 1:
“Absolute Maximum Ratings” are those values beyond which the
safety of the device cannot be guaranteed, they are not meant to imply that
the devices should be operated at these limits. The table of “Recom-
mended Operating Conditions” and “Electrical Characteristics” provides
conditions for actual device operation.
