CD4027BM

Overview

The CD4027BM is a dual J-K master-slave flip-flop manufactured by Harris Corporation, belonging to the 4000B CMOS logic series. It features two independent elements, each handling one bit of data with positive edge triggering. The device operates within a supply voltage range of 3V to 18V and supports a clock frequency up to 24 MHz. Key electrical parameters include a maximum propagation delay of 90ns at 15V with 50pF load, quiescent current of 4µA, and output currents of 6.8mA high and low. It utilizes a 16-SOIC surface-mount package and functions across an operating temperature range of -55°C to 125°C.

Feature Summary

Dual J-K master-slave architecture providing two independent 1-bit storage elements
Positive edge-triggered clock input for reliable state synchronization
Complementary outputs (Q and Q-bar) for versatile logic interfacing
Integrated set and reset inputs for direct control of flip-flop states

Applications

Binary counter circuits requiring dual-stage storage
Shift register configurations in digital systems
Frequency division applications using toggle mode
Data latching and buffering in microprocessor interfaces

Procurement Notes

Verify component authenticity as the CD4027BM is an older legacy part. Confirm that the manufacturer designation matches Harris Corporation specifications rather than Texas Instruments equivalents. Check for RoHS compliance status if required for modern assembly processes. Ensure the 16-SOIC package dimensions align with PCB footprint requirements. Validate that the specific batch meets the -55°C to 125°C operating temperature range.

Selection Notes

Select this component when a dual J-K flip-flop with complementary outputs is required for 4000B series logic designs. Consider the 3V-18V supply range for compatibility with various analog and digital levels. The 24 MHz clock limit suits moderate-speed applications. Evaluate the 16-SOIC package for surface-mount assembly constraints. Compare against newer alternatives if long-term availability is a primary concern.

Part Context

The CD4027BM is part of the extensive 4000B CMOS logic family, known for wide supply voltage operation and high noise immunity. As a dual J-K master-slave flip-flop, it serves as a fundamental building block for sequential logic circuits. Harris Corporation produced this variant before industry consolidation, making it distinct from later Texas Instruments versions while maintaining functional equivalence within the standard specification.
