CD4015BD

Shift Registers Overview

The CD4015BD is a dual 4-stage static shift register belonging to the 4000/14000/40000 series of CMOS logic devices manufactured by Harris Corporation. It features serial-to-parallel conversion capabilities with two independent circuits housed in a single package. The device utilizes a ceramic DIP24 surface mount or through-hole compatible package, specifically identified as CDIP24. It operates within a wide supply voltage range and supports an extended industrial temperature environment suitable for demanding applications.

Shift Registers Feature Summary

• Dual independent 4-stage static shift register architecture
• Serial input to parallel output data conversion functionality
• CMOS technology construction for low power consumption
• Ceramic metal-sealed cofired package design

Shift Registers Applications

• Data storage and buffering in digital systems
• Serial-to-parallel interface conversion modules
• Timing sequence generation circuits
• Industrial control logic interfaces

Shift Registers Procurement Notes

Verify the manufacturer designation carefully, as Harris Corporation's semiconductor assets were acquired by Intersil and subsequently by Renesas Electronics. Ensure the specific suffix 'BD' corresponds to the correct ceramic DIP24 package variant rather than plastic or tape-and-reel alternatives. Confirm RoHS compliance status as original Harris documentation may predate modern environmental directives. Cross-reference datasheets from current asset holders to ensure pinout and electrical specifications remain consistent with legacy requirements.

Shift Registers Selection Notes

Select this component when dual isolated shift registers are required in a single footprint. The ceramic package offers superior thermal stability compared to plastic variants. Verify that the system voltage aligns with standard CMOS logic levels. Consider the physical size constraints of the DIP24 package during PCB layout. Ensure compatibility with existing 4000-series logic families if interfacing with other components.

Shift Registers Part Context

This part belongs to the extensive 4000-series CMOS logic family, known for high noise immunity and wide operating voltage ranges. Harris Corporation was a prominent producer of these analog and mixed-signal components before corporate restructuring. The CD4015 variant specifically addresses needs for compact serial data handling without requiring multiple discrete chips.

Shift Registers Replacement Considerations

Check for equivalents from Texas Instruments such as the CD4015B series. Verify package compatibility between ceramic DIP and plastic SOIC/TSSOP options. Ensure functional parity regarding shift register stages and output configurations.
