3.3v signals to 5v signals

[InitialDriveGTR]

Ok, I successfully got it to receive data using a LVC chip. Now, I have a GPS (CW20 from Navsync - email them for free samples - you just need an antenna) and it has a very vague data sheet. My oscilloscope says it is operating it's serial output at 1.8v. How do i get the PIC to see that? I think a loop back with a max233 might work

Hi,

Use that:

MAX3370/MAX3371 logic level translators
http://pdfserv.maxim-ic.com/en/ds/MAX3370-MAX3371.pdf

The devices accept VCC from +2.5V to +5.5V
and VL from +1.6V to +5.5V, allowing data transfer
between low-voltage ASICs andhigher voltage devices.

Best regards,

Luciano
