4002 IC Dual 4-Input NOR Gate CMOS

4002 IC Dual 4-Input NOR Gate CMOSThe CD4002BE or IC 4002 is a CMOS logic gate IC that contains two independent 4-input NOR gates. It is a widely used chip in digital logic design, providing essential NOR logic functionality in a single compact package. Built on CMOS technology, the IC operates over a wide voltage range (3V to 15V), making it suitable for both TTL and CMOS logic level interfacing.This IC is a foundational component in digital circuit design. The NOR gate, being a universal logic gate, can be used to implement any Boolean function, making the CD4002BE highly versatile. It is widely applied in digital control systems, oscillators, logic combinational designs, and even microcontroller interfacing tasks.Key FeaturesContains two 4-input NOR gates in one ICBuilt with CMOS logic technologyWide supply voltage: 3V to 15VHigh noise immunityLow static power consumptionCompatible with both CMOS and TTL logicDIP-14 package for through-hole applicationsFast switching for digital systemsPin Configuration (CD4002BE)Pin No.NameFunction Description1A1Input A of NOR Gate 12B1Input B of NOR Gate 13C1Input C of NOR Gate 14D1Input D of NOR Gate 15Y1Output of NOR Gate 16NCNot connected7GNDGround8Y2Output of NOR Gate 29D2Input D of NOR Gate 210C2Input C of NOR Gate 211B2Input B of NOR Gate 212A2Input A of NOR Gate 213NCNot connected14VccPositive power supplyProduct Specifications TableSpecificationDetailsFull NameCD4002BE Dual 4-Input NOR GateLogic FamilyCMOSNumber of Gates2Input Count per Gate4Output TypeNOR logicPackage TypeDIP-14Operating Voltage3V – 15V            ‘Operating Temperature-55°C to 125°CLogic CompatibilityTTL & CMOSMounting TypeThrough-HoleApplicationsBuilding digital logic circuitsLogic training kits and academic labsMicrocontroller I/O expansionControl logic designOscillator and timer circuitsAny universal gate-based systemPrototyping and hardware development
