It is a PRESETTABLE BCD 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 a counter. 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. This device will count out of non-BCD counter states in a maximum of two clock pulses in the up mode and DIP ORDER CODES PACKAGE TUBE DIP HCF4510BEY T&R 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. HCF4510B can be cascaded in the ripple mode by connecting all clock inputs in parallel and 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.
