TRS3243E: Difference between MAX3243E and TRS3243E

MAX3243E: Difference between E & non-E version

Part Number: MAX3243E
Other Parts Discussed in Thread: MAX3243,

Hi All,

I would like to know the exact difference between E & non-E versions.


As you mentioned the main difference between E & non-E versions is on the ESD Spec.


And the "Maximum data rate" : 500k bits (E) v.s. 250k bits(non-E).


Except for the above 2 points, could you kindly help to confirm whether I miss something in the datasheet(internal logic/structure...)?


Thank you all.

    Hello,

    You are correct about differences. I confirmed by scanning each of the electrical characteristics.

    MAX3243: 250kbits/sec, RS-232 Bus pins ESD: +/-15kV HBM

    MAX3243E: 500kbits/sec, RS-232 Bus pins ESD: +/-15kV HBM, +/-8kV Contact Discharge, +/-15kV Air Gap Discharge

    Otherwise, these devices are the same. 

    Regards,

    Tyler
