CD4027BCMX

Overview

The CD4027BCMX is a dual J-K flip-flop from the 4000/14000/40000 series, manufactured by Fairchild Semiconductor. It features two independent positive edge-triggered functions with complementary Q and Q outputs. The device utilizes CMOS technology in a 16-pin SOIC package (MS-012). Key electrical parameters include a maximum operating frequency of 2.5 MHz at nominal supply, a load capacitance of 50 pF, and an operating temperature range from -55 °C to +125 °C.

Feature Summary

• Dual independent J-K master/slave flip-flops with set and reset inputs
• Positive edge triggering mechanism for data capture
• Complementary output configuration providing both Q and Q states

Applications

• Digital counting circuits
• Shift register implementations
• Frequency division stages

Procurement Notes

Verify component authenticity against Fairchild Semiconductor specifications. Confirm package integrity for SOIC-16 form factor. Ensure compliance with required operating temperature ranges (-55 °C to +125 °C) for your specific application environment. Cross-reference datasheet revisions to ensure functional compatibility with existing designs.

Selection Notes

Select this component when dual independent bistable elements are required within a single package. The wide operating temperature range supports industrial applications. Verify that the 2.5 MHz maximum frequency meets system timing requirements. Ensure power supply constraints align with standard CMOS logic levels.

Part Context

This part belongs to the widely used 4000-series CMOS logic family, known for high noise immunity and low power consumption. The CD4027 variant specifically provides dual J-K functionality, distinguishing it from simpler D-type or T-type flip-flops in the same series. It serves as a fundamental building block for sequential logic design.

Replacement Considerations

Direct substitutes include other manufacturers' equivalents such as MC14027B or HEF4027B. Verify pinout compatibility and electrical characteristics before substitution. Ensure the replacement part supports the same SOIC-16 package and temperature range.
