No. 370 ezl-80c TTL adaptation 2007-02-28

Hi,

I suppose that connecting directly Rx/Tx from ezl-80c (Vcc:3.3v) to any other device which have Vcc:5V may dammage it.
=> Yes/No ?

Speaking about Rx/Tx TTL adaptation ( 5v / 3.3v), how can i interface ezl-80c with :
1) PIC18F452 (Vcc:5v)
2) MAX 232.


Best regards,
