Looks OK.

But you're using a two-channel translator as a single-channel buffer. A device like the SN74LVC1G34 would be simpler.

Hi Clemens,

Thanks for your valuable feedback.

As per your suggestion we had changed the device from SN74AVC2T244DQE to SN74AVC1T45DCK which will be of single - channel translator.

Please find the image attached below for the latest updated schematics and kindly let me know the feedback.

Thanks and Regards

Looks OK. The two VCC pins are shorted to each other, so you could get away with a single decoupling capacitor.

You are still using a level translator where a simple buffer would suffice, but it's your choice what you put into your BOM.
