4029 IC Binary/Decade Up/Down Counter

4029 IC Binary/Decade Up/Down CounterThe CD4029BE is a presettable, synchronous 4-bit binary/decade up/down counter. This versatile IC can function in either binary mode or BCD (Binary-Coded Decimal) mode, depending on the logic level applied to the MODE input. It includes control inputs for preset (load), enable (clock), direction (up/down), and a carry-out signal, allowing for flexible cascading and custom counting sequences.This counter supports both asynchronous presetting and synchronous counting, making it ideal for applications that require precise timing, multi-digit counters, or frequency division. It integrates easily into digital designs using CMOS technology, which ensures low power consumption, high noise immunity, and compatibility with other logic families.Key FeaturesDual counting modes: BCD and BinaryUp/Down counting controlPresettable with asynchronous load capabilityHigh noise immunity and low static power consumptionCascadable using the carry-out (CO) pinSynchronous counting operationWide voltage supply range: 3V to 15VTTL and CMOS compatibleDIP-16 package Pin Configuration (DIP-16)PinLabelDescription1Q1Output bit 12Q0Output bit 0 (LSB)3Q3Output bit 3 (MSB)4Q2Output bit 25COCarry-Out (for cascading)6DOWN/UPCount Direction Control (LOW = Up)7CLOCKClock input8GNDGround            ‘9PREPreset enable (active LOW)10BPreset Data Input Bit 111CPreset Data Input Bit 212DPreset Data Input Bit 313APreset Data Input Bit 014MODECount Mode Select (LOW = BCD)15ENABLECount Enable (active LOW)16VDDPositive Supply Voltage Product SpecificationsParameterValueIC TypePresettable Up/Down CounterLogic FamilyCMOSPackageDIP-16Operating Voltage3V to 15VCount ModesBinary or BCDCount DirectionControlled by DOWN/UP pinLoad FunctionAsynchronous (via PRE pin)Max Clock Frequency~5 MHz at 10VOperating Temp Range-55°C to 125°COutput Drive±1.5 mA typical ApplicationsDigital counters and dividersEvent counters and timersFrequency countersDigital clocksStepper motor controlData sequencingScoreboards and display systemsBinary or BCD count generation
