CD4027BE

Overview

The CD4027BE is a dual J-K master-slave flip-flop manufactured by Texas Instruments, belonging to the 4000B CMOS logic family. It features two independent flip-flops per package, each equipped with dedicated set and reset inputs for direct state control. The device operates within a supply voltage range of 3V to 18V and supports clock frequencies up to 11 MHz. It utilizes a standard 16-pin PDIP package designed for through-hole mounting, ensuring compatibility with legacy circuit designs.

Feature Summary

• Dual independent J-K master-slave flip-flop architecture
• Direct set and reset input functionality
• Wide operating voltage range from 3V to 18V

Applications

• Binary counter circuits
• Frequency division networks
• Shift register construction

Procurement Notes

Verify the manufacturer marking on the component surface to confirm Texas Instruments origin. Ensure the package matches the specified 16-pin PDIP form factor. Cross-reference the part number against official TI documentation to validate the specific suffix and revision level before integration into production.

Selection Notes

Select this component when a design requires dual bistable elements with asynchronous set and reset capabilities. It is suitable for applications needing wide voltage tolerance and robust CMOS performance. Consider pinout compatibility if replacing older 4000-series equivalents in existing hardware layouts.

Part Context

This component is part of the extensive CD4000B series of CMOS logic devices produced by Texas Instruments. It serves as a fundamental building block for sequential logic systems. The 'BE' suffix typically denotes the specific packaging and commercial grade variant available through authorized distribution channels.

Replacement Considerations

Compatible substitutes include CD4027BC and generic equivalents such as MC14027B or TC4027BP. Verify that alternative sources maintain identical pin configurations and electrical characteristics to ensure seamless interchangeability.
