MAX3243E: Choosing the right Part. TRS3253E, MAX3243E or similar.

Part Number: MAX3243E
Other Parts Discussed in Thread: TRS3253E

Hi,

In our new project we want to connect an industrial "RS-232 V24" to our 3.3V UART logic. We don't need a high speed transmission ( anything above 10Kbs is enough), and our design has to be very cost-efficient.

The RS232 Signal will also use an CTS signal, but only for toggeling a certain variable. 

Right now my problem is to choose the right devices for this task. And i have problems to see the diffrence between the two partnumbers in the title"TRS3253E, MAX3243E"

Maybe someone can help me at this point.

Thanks

Vincent
