4028 IC CMOS BCD-To-Decimal Decoder

4028 IC CMOS BCD-To-Decimal DecoderThe CD4028BE is a BCD-to-decimal decoder IC that converts a 4-bit binary coded decimal input into a one-of-ten decimal output. It activates one of the ten output lines (0 to 9) based on the BCD input ranging from 0000 to 1001. If the input value exceeds the valid BCD range (1010 to 1111), all outputs remain low, preventing invalid output states.This IC is ideal for driving numeric displays, counters, digital clocks, and other BCD-based applications. With high noise immunity, low static power consumption, and wide voltage operating range, the CD4028 operates efficiently in both TTL and CMOS environments. It is built using CMOS technology, offering compatibility with standard logic systems and ensuring reliable operation in a variety of logic-level applications.Key FeaturesConverts BCD (4-bit binary) input to one-of-ten decimal outputsActive high outputs (only one output is HIGH at a time)Outputs 0–9 correspond directly to input values 0000–1001Invalid input detection (outputs low for 1010–1111)High noise immunity and low power consumptionWide supply voltage range: 3V to 15VTTL and CMOS compatibleDIP-16 package for easy integrationPin Configuration (DIP-16)PinLabelDescription1O3Output for decimal 32O2Output for decimal 23O1Output for decimal 14O0Output for decimal 05ABCD Input A (LSB)6BBCD Input B7CBCD Input C8VSSGround9DBCD Input D (MSB)10O9Output for decimal 911O8Output for decimal 812O7Output for decimal 713O6Output for decimal 614O5Output for decimal 515O4Output for decimal 416VDDPositive Power SupplyProduct SpecificationsParameterValueIC FunctionBCD to Decimal DecoderLogic FamilyCMOSPackageDIP-16Supply Voltage Range3V to 15VHigh-Level Output~VDDLow-Level Output~0V         ‘Propagation Delay~200 ns at 10VOperating Temp Range-55°C to 125°COutput Drive Current±1.5 mA (depending on VDD)ApplicationsBCD to decimal decodingDriving 7-segment or numeric displaysDigital countersAlarm systems and number selectorsFrequency display systemsLogic testing or demonstration circuitsLearning and prototyping kits
