CD4047BCN

Multivibrators Overview

The CD4047BC is a low-power CMOS monostable/astable multivibrator manufactured by Fairchild Semiconductor. It operates in either mode using one external resistor and capacitor. The device supports positive or negative edge triggering, retriggerable operation, and free-running or gatable astable modes. It features true and complemented buffered outputs and an oscillator output with double frequency. Recommended operating conditions specify a DC supply voltage range of 3V to 15V and an operating temperature range from -55°C to +125°C.

Multivibrators Feature Summary

• Supports both monostable and astable operation modes with a single external RC network
• Provides true and complemented buffered outputs along with a dedicated oscillator output
• Capable of positive-edge or negative-edge triggering with retriggerable pulse width expansion
• Features high noise immunity and low power consumption suitable for TTL compatibility

Multivibrators Applications

• Frequency discriminators
• Timing circuits
• Time-delay applications
• Envelope detection
• Frequency multiplication and division

Multivibrators Procurement Notes

Verify the package type matches the specific suffix; 'N' indicates a 14-lead Plastic Dual-In-Line Package (PDIP). Confirm RoHS compliance status as manufacturing revisions may affect lead-free specifications. Ensure the ordering code includes the correct suffix if tape and reel packaging is required instead of tube. Check for any specific environmental certifications needed for the target application.

Multivibrators Selection Notes

Select this component when a versatile timing solution requiring minimal external components is necessary. The CD4047BC is suitable for designs needing both monostable and astable functionality within a single IC. Consider the wide supply voltage range and temperature stability for industrial environments. Verify that the output drive current meets the load requirements before finalizing the design.

Multivibrators Part Context

This part belongs to the 4000 series of CMOS logic devices, known for wide voltage operation and low power. The CD4047BC specifically addresses timing generation needs where flexibility between one-shot and free-running modes is required. It serves as a foundational component in analog-digital interface circuits and signal processing systems.

Multivibrators Replacement Considerations

Compatible substitutes include the CD4047B from other manufacturers such as Texas Instruments or Renesas, provided pinouts and electrical characteristics align. Verify that alternative packages like SOIC or ceramic DIP meet mechanical constraints. Ensure functional equivalence in trigger sensitivity and output drive capabilities.
