CD4027BM

Overview

The CD4027BM is a CMOS dual J-K master-slave flip-flop from the Texas Instruments 4000B series. It contains two independent flip-flops in a 16-pin SOIC package. The device supports a supply voltage range of 3 V to 18 V and operates within a temperature range of -55°C to +125°C. Key electrical parameters include a propagation delay of 300 ns, a maximum clock frequency of 3.5 MHz at nominal supply, and output currents of ±1.5 mA. It features differential outputs and single-ended inputs.

Feature Summary

• Dual J-K master-slave configuration for independent data storage
• Differential outputs with set and reset capabilities
• Wide operating voltage range suitable for various logic levels
• Robust performance across extended industrial temperature ranges

Applications

• Digital data storage and register circuits
• Frequency division and counter applications
• Shift register construction
• State machine implementation

Procurement Notes

Verify the specific ordering suffix matches the required package type and temperature grade. Confirm RoHS compliance status if environmental regulations apply to your assembly process. Ensure the supplier provides valid traceability documentation for the Texas Instruments manufacturing source. Cross-reference the datasheet revision date to confirm parameter accuracy against your design requirements.

Selection Notes

Select this component when a dual J-K master-slave topology is required for sequential logic designs. The wide voltage range allows compatibility with both low-power and standard logic systems. Consider the SOIC-16 package for surface-mount assembly constraints. Verify that the 3.5 MHz maximum frequency meets the timing requirements of your clock signal.

Part Context

This part belongs to the Texas Instruments 4000B series of CMOS logic devices. It is functionally equivalent to other manufacturers' CD4027 variants but may differ in pinout or electrical characteristics. The BM suffix typically denotes a plastic small-outline package variant within the broader CD4027 family.

Replacement Considerations

CD4027BPWRG4 is a documented substitute with identical functional specifications.
