MAX3232: Active Status and EOL

The status is shown in the "Status" column in the "Ordering & quality" table on the product page.

The MAX3232E/TRS3232E has better ESD protection than the MAX3232; the LM2904B is a newer version that is much cheaper than the LM2904-N.

MAX3232IPWR is listed as active on ti.com

As Clemens pointed out, you can use the E version of the device.

What is the enhancement in E version . Please explain 

We are using MAX3232IPWR , SN74HC244PWR and LM2904M/NOPB in our existing design. Now we are planning to update the obsolete components with one-to-one replacement in the ECU without modifying the design. So i suggest to confirm the active status of the above mentioned part number. 

Hi Dharanivasan,

The E version is mainly just includes additional air-gap and contact discharge ratings. The non-E version isn't rated for this. 

Other than that, the E version has a lower HBM rating on the TTL pins compared to the non-E.

The E version is pin to pin and should be a direct replacement.

For the other two devices, I will need to reassign this ticket to one of the other product lines responsible for them.

Hi Dharanivasan,

Please suggest a new alternative for LM2904B 

LM2904B is active and it is newly designed via new RFAB process. It should be good for next 20 years or more.

Please let me know if you have other questions.
