CD4027BF3A

Overview

The CD4027BF3A is a dual J-K master-slave flip-flop from the Texas Instruments 4000B series. It operates on a single supply voltage ranging from 3 V to 18 V. The device features differential outputs and supports inverting or non-inverting logic polarities. Key electrical parameters include a propagation delay of 300 ns, with high-level output current of -1.5 mA and low-level output current of 1.5 mA. It functions within an extended temperature range of -55°C to +125°C and is housed in a 16-pin CDIP package.

Feature Summary

• Provides set-reset capability for direct state control
• Enables static operation by retaining state indefinitely regardless of clock level

Applications

• Digital data storage systems
• Shift register construction
• Frequency division circuits
• Binary counter design

Procurement Notes

Verify that the specific suffix BF3A corresponds to the 16-lead ceramic dual in-line package (CDIP) variant. Confirm the manufacturer is Texas Instruments and check RoHS compliance status. Ensure the component matches the 4000B series specifications for voltage and temperature ranges before integration into designs requiring industrial-grade reliability.

Selection Notes

Select this component when dual independent J-K flip-flops with set-reset functionality are required. It is suitable for applications needing static retention without continuous clocking. Consider the CDIP package for through-hole mounting requirements. Verify compatibility with system voltage levels between 3 V and 18 V and ensure the operating temperature range meets environmental constraints.

Part Context

This part belongs to the CD4027B family of CMOS logic devices. It is designed as a dual positive-edge triggered J-K flip-flop with complementary outputs. The 4000B series offers improved noise immunity and lower power consumption compared to earlier iterations. It serves as a fundamental building block for sequential logic circuits in digital electronics.

Replacement Considerations

Compatible substitutes include CD4027BM and CD4027BNSR. These variants offer identical logical functionality but differ in packaging, such as plastic DIP or SOIC formats. Verify pinout compatibility and package dimensions when transitioning between these options.
