MC14020B_05 Datasheet, PDF (1/8 Pages) ON Semiconductor – 14−Bit Binary Counter

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.

Maximum ratings are those values beyond which device damage can occur.
Maximum ratings applied to the device are individual stress limit values (not
normal operating conditions) and are not valid simultaneously. If these limits are
exceeded, device functional operation is not implied, damage may occur and
reliability may be affected.

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
high−impedance circuit. For proper operation, V_in and V_out should be constrained
to the range V_SS v (V_in or V_out) v 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.
