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. Antilock gating is included in the
MC14018B to assure proper counting sequence.

Stresses exceeding Maximum Ratings may damage the device. Maximum
Ratings are stress ratings only. Functional operation above the Recommended
Operating Conditions is not implied. Extended exposure to stresses above the
Recommended Operating Conditions may affect device reliability.

Plastic “P and D/DW” Packages: – 7.0 mW/_C From 65_C To 125_C
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
highimpedance circuit. For proper operation, Vin and Vout should be constrained
to the range VSS v (Vin or Vout) v VDD.
Unused inputs must always be tied to an appropriate logic voltage level (e.g.,
either VSS or VDD). Unused outputs must be left open.
