MC14020B
14-Bit Binary Counter
The MC14020B 14−stage binary counter is constructed with MOS
P−Channel and N−Channel enhancement mode devices in a single
monolithic structure. This part is designed with an input wave shaping
circuit and 14 stages of ripple−carry binary counter. The device
advances the count on the negative−going edge of the clock pulse.
Applications include time delay circuits, counter controls, and
frequency−dividing circuits.

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, V
in
and V
out
should be constrained
to the range V
SS
≤ (V

) ≤ V

.
Unused inputs must always be tied to an appropriate logic voltage level
(e.g., either V

or V
DD
). Unused outputs must be left open.
