Connecting ARM controller to TTL logic levels

I have an LPC2119 controller. The GPIO pins operate on 0-3.3V levels. I wish to interface this to an LCD controller which operates on 0 to 5V (the minimum input value recognised as high is 3.5V), therefore some level conversion is necessary to drive the LCD controller from the LPC2119.

One possible way to do this is to add pull-up resistors to the i/o lines.
An alternative is to use a level translator chip such as a 74LVXC3245MTC, but I'm reluctant to do this as I will require 2 of them and a lot of extra wiring.

So my question is: is using pull-up resistors to interface LPC2119 outputs with 0-5V logic advisable?

What value resistors should I use?

Regards
C
