Description

In the HCC/HCF4029B  series, the HCC4029B (extended temperature range) and HCF4029B (intermediate temperature range) are monolithic integrated circuit, available in 16-lead dual in-line plastic or ceramic package and plastic micro package. The HCC/HCF4029B consists of a four-stage binary or BCD-decade up/down counter with provisions for look-ahead carry in both counting modes. The inputs of HCC/HCF4029B   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. Ahigh 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 PRESET ENABLE signals, are low. Advancement is inhibited when the CARRY-IN or PRESET ENABLE signals are high. The CARRYOUT signal is normally high and goes low when the counter reaches itsmaximum count in the UPmode 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 toVSS whennot 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 to 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 cascading counter packages. Parallel clocking provides synchronous control and hence faster response from all counting outputs. Ripple-clocking allows for longer clock input rise and fall times.
