2 / 12 page HCF4029B 2/12 signal is normally high and 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/DECODE input is high; the counter counts in the decade mode when the BINARY/DECADE input is low. The counter counts Up when to UP/DOWN INPUT is high, and Down when the UP/DOWN INPUT is low. Multiple packages can be connected in either a parallel clocking or a ripple clocking arrangement. Parallel clocking provides synchronous control and, hence, a faster response from all counting outputs. Ripple clocking allows for longer clock input rise and fall times.
