com TECHNICAL DATA KK4516B Presettable Up/Down Counter High-Voltage Silicon-Gate CMOS The KK4516B Presettable Binary Up/Down Counter consists of four synchronously clocked D-type flip-flops (with a gating structure to provide T-type flip-flop capability) connected as counters.
This counter can be cleared by a high level on the RESET line, and can be preset to any binary number present on the jam inputs by a high level on the PRESET ENABLE line.
If the CARRY-IN input is held low, the counter advances up or down on each positive-going clock transition.
Synchronous cascading is accomplished by connecting all clock inputs in parallel and connecting the CARRY-OUT of a less significant stage to the CARRY-IN of a more significant stage.
The KK4516B can be cascaded in the ripple mode by connecting the CARRY-OUT to the clock of the next stage.
If the UP/DOWN input changes during a terminal count, the CARRY-OUT must be gated with the clock, and the UP/DOWN input must change while the clock is high.
This method provides a clean clock signal to the subsequent counting stage.
