Features

t to any binary number present on the jam inputs by a high level on the PRESET ENABLE line. The HCF4510B will count out of non-BCD counter states in a maximum of two clock pulses in the up mode, PIN CONNECTION and a maximum of four clock pulses in the down mode. 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 HCF4510B and HCF4516B can be loaded in th.
