4047 IC Monostable/Astable Multivibrator CMOS

4047 IC Monostable/Astable Multivibrator CMOSThe CD4047BE is a flexible CMOS multivibrator IC that delivers monostable and astable operation modes with precise timing control. Designed using low-power CMOS technology, it offers reliable performance in timer, oscillator, and pulse generator applications.In astable mode, the IC functions as a free-running oscillator with user-defined frequency and duty cycle, determined by external resistor and capacitor values. In monostable mode, it produces a single pulse of specified duration triggered by a rising or falling edge. This versatility allows designers to use a single chip for a variety of timing tasks.Key FeaturesSupports both monostable and astable modesWide supply voltage range: 3V to 15VLow power consumption with CMOS technologyBuffered complementary outputs (Q and Q̅)High noise immunityPrecise frequency and pulse width controlCompatible with TTL and CMOS logic14-pin DIP packagePin Configuration (14-Pin DIP Package)Pin NoSymbolDescription1A̅Negative edge trigger input (monostable)2BPositive edge trigger input (monostable)3CEXTExternal timing capacitor4REXTExternal timing resistor5CONTControl voltage (optional)6QNormal output7Q̅Complementary output8GNDGround     ‘9NCNot connected10ASTABLEAstable mode enable11RESETReset input12MONOMonostable mode enable13NCNot connected14VDDPositive power supplyApplicationsMonostable and astable timersFrequency generatorsPulse width modulationClock pulse generationOscillators for tone generationTime delay circuitsLED and lamp flashersDigital timing in embedded systemsProduct SpecificationsSpecificationValueIC NameCD4047BEFunctionMonostable / Astable MultivibratorTechnologyCMOSOperating Voltage Range3V to 15VOutput Current (per pin)±10 mA (maximum)Input Logic Level High≥ 70% of VDDInput Logic Level Low≤ 30% of VDDPower ConsumptionLow (typical CMOS levels)Package TypeDIP-14Temperature Range-55°C to 125°CFrequency StabilityHigh (depends on R and C values)Propagation Delay~100 ns (varies with VDD)Output TypeBuffered Q and Q̅Reset PinActive High
