What is the difference between MAX3232ESE and MAX3232CSE? Is it interchangeable?

Hi Rose
You could compare data sheets but probably not a lot of difference if any at all except the suffix letters.

As the document in the link says, ESD Protected.
I think the ‘E’ version has high Electro Static Discharge protection whereas the ‘C’ version has normal protection. Electrically they should be the same. Physically too because of the ‘SE’ in the part number.

Hey there @Rose278320!
As mentioned by @James46717, these two chips seemingly only differ regarding ESD. The datasheet shows a difference in temperature range, likely a result of the extra protection.
Though some minor research seems to reveal that neither chip is produced anymore and have both been superseded by the MAX3232ESE+ and MAX3232CSE+, as Mouser lists the original CSE as obsolete, and doesn’t list the original ESE at all.
Strangely, neither of the “+” variants of the chips are ESD-protected.
Hope this helps.

The + versions probably include ESD protection, technology has vastly improved from what is was when I was learning electronics, many decades ago. Also, RS232 is a very old transmission standard and has been surpassed by other better standards today.
