CD4027BMT

Overview

The CD4027BMT is a dual J-K master-slave flip-flop manufactured by Texas Instruments in the 4000B CMOS logic series. It features two independent circuits within a single SOIC-16 package. The device operates on a supply voltage range of 3 V to 18 V and supports a wide operating temperature range from -55 °C to +125 °C. 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. The inputs are single-ended, while outputs provide differential signals with inverting and non-inverting polarities.

Feature Summary

• Dual J-K master-slave flip-flop architecture providing two independent storage elements
• Differential output configuration offering both inverting and non-inverting signal paths
• Wide power supply tolerance supporting operation from 3 V to 18 V
• Military-grade temperature rating ensuring functionality across extreme environmental conditions

Applications

• Digital data storage and register applications
• Frequency division and counter circuit designs
• State machine implementation in control systems
• Shift register construction for serial-to-parallel conversion

Procurement Notes

Verify that the specific part number suffix matches the required package type and thermal rating. Confirm compliance with RoHS directives if lead-free composition is mandatory for the assembly process. Ensure the supplier provides traceability documentation for military or aerospace grade variants if applicable. Cross-reference the manufacturer's latest datasheet to confirm active status and any potential obsolescence notices before finalizing procurement orders.

Selection Notes

Select this component when dual independent J-K flip-flops are required in a compact surface-mount format. The wide voltage range makes it suitable for variable power environments. Consider the 300 ns propagation delay for timing constraints. Verify that the SOIC-16 footprint aligns with the PCB layout requirements. Evaluate the differential output capability against system interface needs compared to single-ended alternatives.

Part Context

This component belongs to the Texas Instruments 4000B series of CMOS logic devices. The 4000B series is known for broad compatibility with standard TTL logic levels and robust performance in harsh environments. The CD4027 variant specifically addresses sequential logic needs, serving as a fundamental building block for memory and counting functions within larger digital integrated circuit systems.

Replacement Considerations

Compatible substitutes include the CD4027BM (SOIC-16) and CD4027BPWR (TSSOP-16). Verify pinout compatibility and electrical specifications before substitution. Other manufacturers such as STMicroelectronics offer equivalent parts like the HCC4027B.
