MC74HC589ADR2

Shift Registers Overview

The MC74HC589ADR2 is an obsolete 8-bit shift register manufactured by onsemi, belonging to the 74HC logic series. It features tri-state outputs and operates within a supply voltage range of 2V to 6V. The component is housed in a 16-SOIC surface-mount package with a width of 3.90mm. Designed for industrial environments, it supports an operating temperature range from -55°C to 125°C. This device functions as a parallel-to-serial or serial-to-serial converter, containing one internal element per package.

Shift Registers Feature Summary

• Provides tri-state output capability for bus-driven applications
• Supports both parallel-to-serial and serial-to-serial data conversion modes
• Operates across a wide industrial temperature range

Shift Registers Applications

• Industrial control systems requiring data shifting
• Consumer electronics utilizing 74HC logic families
• Communication interfaces needing serial data conversion

Shift Registers Procurement Notes

This specific part number is officially discontinued and no longer manufactured by onsemi. Verification of current availability should focus on alternative sources or direct replacement components rather than new production units. Buyers must confirm the exact suffix and RoHS compliance status when sourcing substitutes, as environmental regulations may differ between legacy and modern versions of this component family.

Shift Registers Selection Notes

Designers seeking a functional equivalent should consider the MC74HC589ADR2G, which serves as a direct replacement. Selection criteria should prioritize the 16-SOIC package compatibility and the 2V to 6V operating voltage range. Ensure that the substitute component meets the required -55°C to 125°C temperature specifications for the intended application environment.

Shift Registers Part Context

The MC74HC589ADR2 belongs to the broader 74HC589 product line, which includes various packaging options such as SOEIAJ and PDIP variants. These components are standardized 8-bit shift registers designed for general-purpose logic applications. The manufacturer has transitioned production to newer iterations, rendering the non-G suffix version obsolete in active manufacturing channels.

Shift Registers Replacement Considerations

The MC74HC589ADR2G is listed as a direct replacement for this obsolete component. Verify pinout compatibility and ensure the RoHS-compliant variant meets all environmental requirements for the target assembly.
