Binary Or Bcd Decade Presettable Up/down Counter

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 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 EN- ABLE 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-INand PRESET 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 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 con- nected toVSS whennot in use. Binary counting is ac- complished when the BINARY/DECADE input is high ; the Counter counts in the decade mode when the BINARY/DECADE input is low. By STMicroelectronics
