It has the same pinout, but not the same supply voltage range.

Hello,

Thank you for your reply. I confirmed that suuply voltage range is different.

On TI.com cross reference search, CD74HC4538 is marked as "S". Is it true?

Also, could you tell me whetehr there is EOL plan or not?

Thanks and best regards,
