HCF4029B is a monolithic integrated circuit fabricated in Metal Oxide Semiconductor technology available in DIP and SOP packages. 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 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 advances 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 CARRY-OUT
