CMOS Presettable Up/Down Counter
Description
CD4029BMS consists of a four-stage binary or BCD-decade up/ down counter with provisions for look-ahead carry in both counting modes. The inputs consist of a single CLOCK, CARRY-IN (CLOCK ENABLE), BINARY/DECADE, UP/DOWN, PRESET ENABLE, and four individual JAM signals. Q1, Q2, Q3, Q4 and a CARRY OUT signal are provided as outputs. A high PRESET ENABLE signal allows information on the JAM INPUTS to preset the counter to any state asynchronously with the clock. A low on each JAM line, when the PRESET-ENABLE signal is high, resets the counter to its zero count. The counter is advanced one count at the positive transition of the clock when the CARRY-IN and PRE-SET ENABLE signals are low. Advancement is inhibited when the CARRY-IN or PRESET ENABLE signals are high. The CARRY-OUT signal is normally high and goes low when the counter reaches its maximum count in the UP mode or the minimum count in the DOWN mode provided the CARRY-IN signal is low. The CARRY-IN signal in the low state can thus be considered a CLOCK ENABLE. The CARRY-IN terminal must be connected to VSS when not in use. Binary counting is accomplished when the BINARY/DECADE input is high; the counter counts in the decade mode when the BINARY/DECADE input is low. The counter counts up when the UP/DOWN input is high, and down when the UP/DOWN input is low. Multiple packages can be connected in either a parallelclocking or a ripple-clocking arrangement as shown in Figure 17. Parallel clocking provides synchronous control and hence faster response from all counting outputs. Ripple-clocking allows for longer clock input rise and fall times. The CD4029BMS is supplied in these 16-lead outline packages: Braze Seal DIP H4X Frit Seal DIP H1F Ceramic Flatpack H6W

The CD4029BMS CLOCK and UP/DOWN inputs are used directly in most applications. In applications where CLOCK UP and CLOCK DOWN inputs are provided, conversion to the CD4029BMS CLOCK and UP/DOWN inputs can easily be realized by use of the circuit in Figure 11. CD4029BMS changes count on positive transitions of CLOCK UP or CLOCK DOWN inputs. For the gate configuration in Figure 12, when counting up the CLOCK DOWN input must be maintained high and conversely when counting down the CLOCK UP input must be maintained high.

*CARRY OUT LINES AT THE 2ND, 3RD, ETC, STAGES MAY HAVE A NEGATIVE-GOING GLITCH PULSE RESULTING FROM DIFFERENTIAL DELAYS OF DIFFERENT CD4029BMS IC'S. THESE NEGATIVE GOING GLITCHES DO NOT AFFECT PROPER CD4029BMS OPERATION. HOWEVER, IF THE CARRY OUT SIGNALS ARE USED TO TRIGGER OTHER EDGE-SENSITIVE LOGIC DEVICES, SUCH AS FF'S OR COUNTERS, THE CARRY OUT SIGNALS SHOULD BE GATED WITH THE CLOCK SIGNAL USING A 2-INPUT OR GATE SUCH AS CD4071BMS.

BINARY/ DECADE RIPPLE CLOCKING MODE: THE UP/DOWN CONTROL CAN BE CHANGED AT ANY COUNT. THE ONLY RESTRICTION ON CHANGING THE UP/DOWN CONTROL IS THAT THE CLOCK INPUT TO THE FIRST COUNTING STAGE MUST BE HIGH. FOR CASCADING COUNTERS OPERATING IN A FIXED UP-COUNT OR DOWN-COUNT MODE, THE OR GATES ARE NOT REQUIRED BETWEEN STAGES, AND CO IS CONNECTED DIRECTLY TO THE CL INPUT OF THE NEXT STAGE WITH CI GROUNDED.
