Overview
CD4510BMS, CD4516BMS Data Sheet December 1992 File Number 3338 CMOS Presettable Up/Down Counters CD4510BMS Presettable BCD Up/Down Counter and the CD4516BMS Presettable Binary 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.
These counters 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.
The CD4510BMS 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 CD4510BMS and CD4516BMS 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.
(See Figures 13, 14.
) These devices are similar to types MC14510 and MC14516.
