NSC CD4024

CD4024BM/CD4024BC
7-Stage Ripple Carry Binary Counter
General Description
Features
The CD4024BM/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.

*AC Parameters are guaranteed by DC correlated testing.
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 ‘‘Recommended Operating Conditions’’ and ‘‘Electrical Characteristics’’ provides conditions for actual device
operation.
Note 2: VSS e 0V unless otherwise specified.
Note 3: IOH and IOL are tested one output at a time.
Note 4: Capacitance is guaranteed by periodic tesing.
