Shift Registers Procurement Notes

Verify manufacturer authenticity and lot traceability when sourcing this legacy Harris component. Confirm package integrity and pin compatibility with existing PCB footprints. Ensure environmental compliance status matches project requirements given the historical manufacturing date. Request detailed datasheets to validate electrical characteristics against current design specifications.

Shift Registers Selection Notes

Select this part for applications requiring extensive serial-to-parallel conversion or long delay lines. Consider the 64-stage depth relative to system timing constraints. Evaluate CMOS voltage ranges against available supply rails. Assess thermal management needs based on operating temperature limits defined in the official documentation.

Shift Registers Part Context

This device is part of the broader CD4000 series family of CMOS logic functions. It shares architectural similarities with other shift registers in the lineup but offers specific 64-bit capacity. The Harris Corporation branding indicates its origin from the semiconductor division later acquired by Texas Instruments.

Shift Registers Replacement Considerations

Check for direct equivalents such as the CD4031B types documented by Texas Instruments. Verify pinout compatibility before substitution. Ensure functional parity regarding stage count and input/output configurations.
