MC14040B
12-Bit Binary Counter
The MC14040B 12−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 12 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−driving 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
in
or V
out
)
≤
V
DD
.
Unused inputs must always be tied to an appropriate logic voltage level
(e.g., either V
SS
or V
DD
). Unused outputs must be left open.
(Note: Microdot may be in either location)

APPLICATIONS INFORMATION
TIME−BASE GENERATOR
A 60 Hz sinewave obtained through a 1.0 Megohm
resistor connected directly to a standard 120 Vac power line
is applied to the clock input of the MC14040B. By selecting
outputs Q5, Q10, Q11, and Q12 division by 3600 is
accomplished. The MC14012B decodes the counter
outputs, produces a single output pulse, and resets the binary
counter. The resulting output frequency is 1.0 pulse/minute.
