CD4015AD3

Shift Registers Overview

The CD4015AD3 is a dual serial shift register manufactured by Harris Corporation, belonging to the 4000/14000/40000 series. It features two independent 8-bit shift registers with serial input and parallel output capabilities. The device operates on CMOS technology and is housed in a 16-pin Plastic Dual In-Line Package (PDIP). It supports positive edge-triggered clocking for data shifting. The component is designed for digital logic applications requiring serial-to-parallel conversion within standard industrial temperature ranges.

Shift Registers Feature Summary

• Dual independent 8-bit serial shift register architecture
• Positive edge-triggered clock operation for reliable data shifting
• CMOS construction ensuring low power consumption
• Parallel output configuration for simultaneous data access

Shift Registers Applications

• Serial-to-parallel data conversion circuits
• Digital signal processing interfaces
• Microcontroller peripheral expansion systems
• Sequential logic control applications

Shift Registers Procurement Notes

Verify the manufacturer designation as Harris Corporation or its successors, as original Harris semiconductor assets were acquired. Confirm the package type matches the specified PDIP-16 form factor. Ensure the device meets the required operating temperature specifications for the intended environment. Check for RoHS compliance status if applicable to the project requirements. Validate the part number suffix against current distributor listings to ensure correct revision matching.

Shift Registers Selection Notes

Select this component when dual independent 8-bit shift functionality is required in a single package. The CMOS technology offers advantages in power efficiency compared to older bipolar alternatives. Consider the PDIP-16 package for through-hole prototyping or high-reliability manual assembly needs. Verify compatibility with the system's voltage levels and clock speeds before integration into the design.

Shift Registers Part Context

This component is part of the extensive 4000-series CMOS logic family, known for wide supply voltage ranges and compatibility with various digital systems. Harris Corporation was a significant producer of such logic devices before industry consolidations. The CD4015 specifically addresses the need for compact serial data handling solutions in embedded and industrial control environments.

Shift Registers Replacement Considerations

Equivalent parts include the SN74HC595 for single-channel applications, though pinouts differ. The CD4015B may serve as a direct replacement if available from current manufacturers holding the rights to the original specifications. Verify electrical characteristics and package dimensions carefully when substituting.
