MM74HC589N

Shift Registers Overview

The MM74HC589N is an 8-bit parallel-in serial-out shift register manufactured by Fairchild Semiconductor. It features a single element with tri-state outputs and operates within a supply voltage range of 2V to 6V. The device is housed in a 16-pin PDIP package designed for through-hole mounting. It supports an operating temperature range from -40°C to 85°C and belongs to the 74HC logic series.

Shift Registers Feature Summary

• Parallel data loading capability via dedicated inputs
• Serial output shifting with tri-state control
• CMOS construction for low power consumption

Shift Registers Applications

• Bus-oriented systems requiring data serialization
• LED display scanning circuits
• Data acquisition multiplexing

Shift Registers Procurement Notes

Verify component authenticity as this part is marked as obsolete. Confirm package integrity and pin alignment against the 16-PDIP specification. Check datasheet revisions for any functional updates or environmental compliance changes prior to integration into new designs.

Shift Registers Selection Notes

Select this component when an 8-bit shift register with tri-state outputs is required in a through-hole DIP package. Ensure the system voltage falls within the 2V to 6V range. Consider availability constraints due to its discontinued status and evaluate alternative sources if long-term supply stability is critical.

Shift Registers Part Context

This component is part of the 74HC family, known for high-speed CMOS operation compatible with standard TTL logic levels. The MM74HC589N specifically provides parallel-to-serial conversion functionality. It is distinct from similar devices like the MM74HC597 which lacks tri-state outputs.

Shift Registers Replacement Considerations

HD74HC589RP is a documented substitute offering identical logical function in a surface-mount SOIC package.
