Procurement Notes

This component is officially designated as obsolete and no longer manufactured by Renesas Electronics. Procurement is limited to existing stock from authorized distributors or secondary market suppliers. Buyers should verify the authenticity of available units and check for Product Change Notices (PCN) related to end-of-life status before placing orders.

Selection Notes

Designers seeking this specific part must account for its discontinued status. The datasheet indicates that the manufacturer recommends the 23S09-1HPGGI8 as a replacement. Selection should focus on verifying pin compatibility and electrical parameter alignment with the recommended substitute if the original part is unavailable.

Part Context

The 23S05E-1HDCGI8 belongs to the IDT/Renesas 23S09 family of zero-delay buffers. These components are engineered to eliminate propagation delay skew between input and output clocks using internal phase-locked loops. This specific variant provides nine buffered outputs from a single input source.

Replacement Considerations

Renesas recommends the 23S09-1HPGGI8 as the official replacement for this obsolete part number.
