DESCRIPTION
The HCF4018B is a monolithic integrated circuit
fabricated in Metal Oxide Semiconductor
technology available in DIP and SOP packages.
The HCF4018B consist of 5 Johnson counter
stages, buffered Q outputs from each stage, and
counter preset control gating. CLOCK, RESET,
DATA, PRESET ENABLE, and 5 individual JAM
inputs are provided. Divide by 10, 8, 6, 4 or 2
counter configuration can be implemented by
feeding the Q5, Q4, Q3, Q2, Q1 signals,
respectively, back to the data input.
Divide-by-9, 7, 5, or 3 counter configurations can
be implemented by the use of a HCF4011B gate

package to properly gate the feedback connection
to the DATA input. Divide-by-functions greater
than 10 can be achieved by use of multiple
HCF4018B units. The counter is advanced one
count at the positive clock signalstransition.
Schmitt trigger action on the clock line permits
unlimited clock rise and fall times. A high RESET
signal clears the counter to an all-zero condition. A
high PRESENT-ENABLE signal allows
information on the JAM inputs to preset the
counter.
Anti-lock gating is provided to assure the proper
counting sequence.
