... MOTOROLA SEMICONDUCTOR TECHNICAL DATA Presettable 4-Bit Down Counters The MC14522B BCD counter and the MC14526B binary counter are constructed with MOS P–channel and N–channel enhancement mode devices in a monolithic structure. These devices are presettable, cascadable, synchronous down counters with a decoded “0” state output for divide–by–N applications. In single stage applications the “ ...

Cascade Feedback (Pin 13) — If the Cascade Feedback input is high, a high level is generated at the “0” output when the count is all zeroes. If Cascade Feedback is low, the “ ...

... LOAD MC14522B MC14526B 8 APPLICATIONS INFORMATION The Inhibit pin may be used to stop pulse counting. When this pin is taken high, decrementing is inhibited. Cascaded, Presettable Divide–By–N Figure 12 shows a three stage cascade application. Taking Reset high loads N. Only the first stage’s Reset pin (least sig- nificant counter) must be taken high to cause the preset for all stages, but all pins could be tied together, as shown ...
