CMOS presettable BCD up/down counter, CD4510BE, Texas Instruments

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 product 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. 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.
