CD4031BPW

Shift Registers Overview

The CD4031BPW is a CMOS 64-stage static shift register manufactured by Texas Instruments. It features serial input and serial output capabilities, functioning as a single-element, 4-bit wide shift register architecture within the broader 64-bit structure. The device operates within an extended temperature range of -55°C to +125°C, ensuring reliability in harsh environments. It utilizes a 16-pin TSSOP surface-mount package, designed for efficient PCB space utilization. The component supports standard CMOS logic levels and is part of the established CD4000 series family.

Shift Registers Feature Summary

• Provides 64-stage serial-to-serial data shifting capability
• Operates reliably across an extended industrial temperature range
• Utilizes low-power CMOS technology for static operation

Shift Registers Applications

• Digital signal processing delay lines
• Data storage and buffering systems
• Parallel-to-serial or serial-to-parallel conversion circuits

Shift Registers Procurement Notes

Verify current manufacturing status as the CD4031BPW has been identified as obsolete or scheduled for discontinuation by the manufacturer. Confirm availability of recommended substitutes such as the CD4031BPWR variant before finalizing procurement plans. Ensure compatibility with existing design constraints when transitioning to replacement components.

Shift Registers Selection Notes

Select this component for applications requiring long-duration data retention or precise timing delays using serial architectures. Consider the TSSOP-16 package dimensions for layout constraints. Evaluate the need for extended temperature tolerance if operating in industrial or automotive environments where standard commercial grades are insufficient.

Shift Registers Part Context

This component belongs to the Texas Instruments CD4000 series of CMOS digital logic devices. The CD4031 specifically addresses the need for high-capacity shift registers in sequential logic designs. It serves as a fundamental building block for complex digital systems requiring data movement and temporary storage without volatile memory dependencies.

Shift Registers Replacement Considerations

The CD4031BPWR is listed as a manufacturer-recommended substitute for the CD4031BPW. Verify pinout and electrical specifications match before integration.
