The HCC/HCF40102B, and HCC/HCF40103B consist of an 8-stage synchronous down counter with a single output which is active when the internal count is zero. The HCC/HCF40102B is configured as two cascaded 4-bit BCD counters, and the HCC/HCF40103B contains a single 8-bit binary counter. Each type has control inputs for enabling or disabling the clock, for clearing the counter to its maximum count, and for presetting the counter either synchronously or asynchronously. All control inputs and the CARRY-OUT/ZERO-DETECT output are active-low logic. In normal operation, the counter is decremented by one count on ...
