MC14017B
Decade Counter
The MC14017B is a five−stage Johnson decade counter with
built−in code converter. High speed operation and spike−free outputs
are obtained by use of a Johnson decade counter design. The ten
decoded outputs are normally low, and go high only at their
appropriate decimal time period. The output changes occur on the
positive−going edge of the clock pulse. This part can be used in
frequency division applications as well as decade counter or decimal
decode display applications.

Stresses exceeding those listed in the Maximum Ratings table may damage the
device. If any of these limits are exceeded, device functionality should not be
assumed, damage may occur and reliability may be affected.
1. Temperature Derating: “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
high−impedance circuit. For proper operation, Vin and Vout should be constrained
to the range VSS (Vin or Vout) 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.
