MC14018B
Presettable Divide-By-N
Counter
The MC14018B contains five Johnson counter stages which are
asynchronously presettable and resettable. The counters are
synchronous, and increment on the positive going edge of the clock.
Presetting is accomplished by a logic 1 on the preset enable input.
Data on the Jam inputs will then be transferred to their respective Q
outputs (inverted). A logic 1 on the reset input will cause all Q outputs
to go to a logic 1 state.
Division by any number from 2 to 10 can be accomplished by
connecting appropriate Q
outputs to the data input, as shown in the
Function Selection table. Anti–lock gating is included in the
MC14018B to assure proper counting sequence.

2. Maximum Ratings are those values beyond which damage to the device
may occur.

This device contains protection circuitry to guard against damage due to high
static voltages or electric fields. However, precautions must be taken to avoid
applications of any voltage higher than maximum rated voltages to this
high–impedance circuit. For proper operation, Vin and V
out
should be constrained
to the range V

v (Vin or V

) v VDD.
Unused inputs must always be tied to an appropriate logic voltage level (e.g.,
either V
SS
or VDD). Unused outputs must be left open.
