CD4031BNSR

Shift Registers Overview

The CD4031BNSR is a static shift register from the Texas Instruments CD4000B series, housed in a 16-lead SOIC surface-mount package. It contains 64 D-type master-slave flip-flop stages and one additional D-type master flip-flop stage. The device operates on a supply voltage range of 3 V to 18 V and supports an operating temperature range from -55°C to +125°C.

Shift Registers Feature Summary

• Contains 64 master-slave flip-flop stages for serial data storage
• Includes one dedicated master-only flip-flop stage
• Supports wide supply voltage operation
• Rated for extended industrial temperature ranges

Shift Registers Applications

• Serial-to-parallel data conversion circuits
• Parallel-to-serial data transmission systems
• Digital delay line implementations
• Sequence generation logic

Shift Registers Procurement Notes

Verify the specific suffix 'NSR' against the manufacturer's current datasheet to confirm the tape-and-reel packaging configuration and lead-free status. Ensure the design accommodates the 16-lead SOIC footprint dimensions and thermal requirements for the specified operating temperature range.

Shift Registers Selection Notes

Select this component when a high-density shift register with a dedicated master stage is required within the CD4000B family. Consider the 16-lead SOIC package constraints and the wide voltage tolerance suitable for various digital logic interfaces.

Shift Registers Part Context

This part belongs to the CD4000B CMOS logic family, known for low power consumption and wide supply voltage flexibility. The CD4031B variant specifically provides extensive shifting capabilities compared to standard counters or simpler registers in the same series.

Shift Registers Replacement Considerations

Check for CD4031BE (plastic DIP) or CD4031BM (SOIC, non-reel) if pinout compatibility is maintained but packaging differs. Verify functional equivalence with other generic 64-stage CMOS shift registers only after confirming pin definitions.
