CD4027BEE4

Overview

The CD4027BEE4 is a dual J-K master-slave flip-flop from the Texas Instruments 4000 series of CMOS logic devices. It integrates two independent flip-flops within a single 16-pin PDIP package, designed for through-hole mounting. The component operates with a supply voltage range of 3 V to 18 V and supports an operating temperature range from -55 °C to +125 °C. Key electrical specifications include a propagation delay of 300 ns, a high-level output current of -1.5 mA, and a low-level output current of 1.5 mA. The device features differential outputs and single-ended inputs.

Feature Summary

• Dual independent J-K master-slave flip-flop configuration
• Differential output capability for complementary signal generation
• Wide power supply voltage tolerance for flexible system integration
• Extended industrial temperature range operation

Applications

• Digital data storage and register circuits
• Frequency division and counter stages
• State machine implementation in control logic
• Pulse synchronization and timing circuits

Procurement Notes

Verify the specific suffix 'E4' confirms lead-free compliance and RoHS status as per manufacturer documentation. Confirm the PDIP-16 package type matches your PCB footprint requirements. Ensure the ordering information aligns with the exact part number to avoid pinout or functional discrepancies. Cross-reference the datasheet revision date for any updates in electrical characteristics or recommended operating conditions.

Selection Notes

Select this component when a dual flip-flop solution is required in a through-hole design. The wide voltage range suits applications where supply rails vary between 3 V and 18 V. Consider the 300 ns propagation delay for timing constraints. Compare against other packages like SOIC or TSSOP if surface mount technology is preferred instead of through-hole mounting.

Part Context

This device belongs to the standard 4000 series CMOS logic family, known for high noise immunity and broad operating voltage ranges. The CD4027 variant specifically provides dual J-K functionality, distinguishing it from single flip-flop parts or other logic types like D-type or SR-type within the same series. It serves as a fundamental building block for sequential logic circuits in general-purpose digital systems.

Replacement Considerations

CD4027BE is the non-compliant equivalent. CD4027BNSR offers the same function in an SOIC-16 surface-mount package. CD4027BPWR provides the function in a TSSOP-16 package.
