Procurement Notes

This component is officially marked as obsolete and no longer manufactured by Renesas Electronics Corporation. Procurement should focus on identifying valid substitute part numbers from other manufacturers such as Texas Instruments or Rochester Electronics. Verify that alternative components meet the required pinout, electrical specifications, and package dimensions before integration into existing designs.

Selection Notes

Designers must account for the end-of-life status when selecting this component. Direct replacements may require schematic modifications if pinouts differ. Evaluate available substitutes based on propagation delay, output drive strength, and operating temperature range. Ensure that any replacement device maintains compatibility with the 5V logic levels and SOIC-20 footprint constraints of the original design.

Part Context

The 74FCT574CTSOG8 belongs to the 74FCT logic series, which utilizes CMOS technology for high-speed operation. As an octal D-register, it provides eight independent flip-flops with common clock and reset inputs. The device is designed for applications requiring reliable data retention and transfer in digital systems, typically found in memory interfaces and control logic blocks.

Replacement Considerations

Available substitutes include CY74FCT2574CTSOC from Rochester Electronics. Verify functional equivalence regarding pin configuration and electrical characteristics before substitution.
