CD4015AK

Shift Registers Overview

The CD4015AK is a dual 4-stage static shift register manufactured by Harris Corporation, belonging to the 4000/14000/40000 series. It features two independent registers with serial inputs and parallel outputs. The device utilizes CMOS technology and operates within a supply voltage range of 3V to 18V. It supports a typical clock rate of 12MHz at VDD-VSS = 10V. The package type is CDFP14, and it functions as a master-slave flip-flop circuit.

Shift Registers Feature Summary

• Dual independent 4-stage serial-input/parallel output registers
• High-voltage CMOS construction with 20V rating capability
• Fully static operation for reliable data retention
• Symmetrical output characteristics standardized across operating conditions

Shift Registers Applications

• Serial-to-parallel data conversion circuits
• Parallel-to-serial data transmission systems
• Digital timing and sequencing logic applications
• General-purpose shift register expansion in digital systems

Shift Registers Procurement Notes

Verify manufacturer authenticity as Harris Corporation has undergone corporate restructuring. Confirm package integrity for the CDFP14 ceramic flatpack. Check RoHS compliance status as original documentation may predate modern regulations. Ensure storage conditions maintain moisture sensitivity level requirements for ceramic packages.

Shift Registers Selection Notes

Select this component when dual independent shift registers are required in a single package. Consider the CDFP14 ceramic package for high-reliability or military-grade applications requiring hermetic sealing. Verify voltage compatibility with the 3V to 18V operating range. Evaluate pinout compatibility if replacing equivalent parts from other manufacturers in the 4000 series family.

Shift Registers Part Context

The CD4015AK belongs to the widely used 4000 series CMOS logic family produced by Harris Corporation. This series established standards for low-power digital logic in industrial and commercial applications. The AK suffix typically denotes a specific package variant or qualification grade within the CD4015 product line, distinguishing it from plastic or alternative ceramic versions.

Shift Registers Replacement Considerations

Equivalent parts include CD4015BCN (onsemi) and CD4015BPWR (Texas Instruments). Verify pin compatibility and package dimensions before substitution. Note that some equivalents may use plastic packages instead of ceramic, affecting thermal and environmental performance.
