CD4013AK

Overview

The CD4013AK is a dual D-type flip-flop integrated circuit manufactured by Harris Corporation. It belongs to the 4000B series of CMOS logic devices and features two independent positive-edge triggered D flip-flops within a single package. The device supports asynchronous set and reset functions, allowing for direct control of output states independent of the clock signal. It operates with a wide supply voltage range and provides complementary outputs (Q and Q-bar) for each flip-flop. The component is designed for robust performance in digital logic applications requiring data storage, shift registers, or counters.

Feature Summary

• Dual independent D-type flip-flops with positive-edge triggering
• Asynchronous set and reset capabilities for direct state control
• Complementary Q and Q-bar outputs for flexible logic interfacing
• CMOS construction ensuring low static power consumption

Applications

• Digital shift register circuits
• Binary counter designs
• Data storage and latching applications
• Timing and delay generation circuits

Procurement Notes

Verify the manufacturer origin carefully, as Harris Corporation's semiconductor assets were acquired by other entities. Confirm that the specific CD4013AK variant matches the required pinout and electrical specifications for your design. Check for RoHS compliance status if modern environmental standards are mandatory. Ensure the package type aligns with your PCB footprint requirements before finalizing procurement.

Selection Notes

Select this component when a dual D-type flip-flop solution is required within the standard 4000B CMOS logic family. It is suitable for designs needing asynchronous preset and clear functions alongside standard clocked data transfer. Consider the operating temperature range and supply voltage compatibility with your system architecture. This part is appropriate for general-purpose digital logic where moderate speed and low power are prioritized over high-frequency performance.

Part Context

The CD4013AK is part of the extensive 4000B series of CMOS logic integrated circuits. This series is widely recognized for its versatility and compatibility across various digital systems. As a dual D-type flip-flop, it serves as a fundamental building block for sequential logic circuits. The 'AK' suffix typically denotes a specific package or processing variant within the Harris product line, distinguishing it from other packaging options like DIP or SOIC.

Replacement Considerations

Compatible substitutes include the CD4013BE from Texas Instruments and the TC4013BP from Toshiba. These alternatives offer similar logical functionality and pin configurations. Verify that any replacement maintains the same asynchronous set/reset behavior and output drive characteristics to ensure seamless integration into existing designs.
