CD4029BMS
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 count-
ing 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 pro-
vided 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 parallel-
clocking 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.
