CD40103B CMOS 8 级可预置 8 位二进制同步递减计数器

CD40102B, and CD40103B consist of an 8-stage synchronous down counter with a single output which is active when the internal count is zero. The CD40102B is configured as two cascaded 4-bit BCD counters, and the CD40103B 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-DEFECT output are active-low logic.

In normal operation, the counter is decremented by one count on each positive transition of the CLOCK. Counting is inhibited when the CARRY-IN/COUNTER ENABLE (CI/CE)\ input is high. The CARRY-OUT/ZERO-DEFECT (CO/ZD)\ output goes low when the count reaches zero if the CI/CE\ input is low, and remains low for one full clock period
