Логическая ИС CD4510BE

Двоичный суммирующий/вычитающий счетчик ,, 8МГц, 3В - 18В, DIP-16

The CD4510BE is a CMOS Presettable BCD Up/Down Counter consist 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 pre-set to any binary number present on the jam inputs by a high level on the PRESET ENABLE line. The CD4510B will count out of non-BCD counter states in a maximum of two clock pulses in the up mode 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 counter can be cascaded in the ripple mode by connecting the CARRY-OUT to the clock of the next stage.

• Synchronous internal carry propagation
