CD4027BNSR

Overview

The CD4027BNSR is a dual J-K master-slave flip-flop from the Texas Instruments CD4000B series, housed in a 16-pin SOIC package. It operates on a single power supply ranging from 3 V to 18 V. The device features differential outputs with inverting and non-inverting polarities. Key electrical parameters 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. It supports surface-mount installation and functions within a temperature range of -55 °C to +125 °C.

Feature Summary

• Dual independent J-K master-slave flip-flops integrated into a single unit
• Differential output configuration providing both inverting and non-inverting signals
• Wide operating voltage capability supporting standard logic levels
• Extended industrial temperature rating for harsh environment reliability

Applications

• Parallel-to-serial data conversion circuits
• Frequency division and counting applications
• Digital state storage and memory elements
• Sequence control logic systems

Procurement Notes

Verify the specific suffix 'NSR' corresponds to the SOIC-16 surface mount package and reel packaging format. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure input signal levels remain within the specified 3 V to 18 V operational range to prevent device damage or undefined logic states during operation.

Selection Notes

Select this component when dual independent bistable memory elements are required in a compact surface-mount footprint. The wide voltage range allows compatibility with various digital logic families. Consider the 300 ns propagation delay for timing constraints. This part is suitable for designs needing differential outputs without external inversion circuitry.

Part Context

This component belongs to the CD4000B series of CMOS logic devices manufactured by Texas Instruments. It serves as a fundamental building block for sequential logic circuits.
