Hello.
I am new to electronic hardware developing (I worked all my time with software). I have been playing with an enc28j60 module in arduino, but now I want to integrate the enc28j60 on my custom pic board. All schemes I have found so far are using a 74hct245, and my question is if I put the pic in 3.3 volts if I can use the enc28j60 without the 74hct245.

Thanks

Short answer, yes you can skip the 74hct245...

See page 7 (Note #2) of the datasheet and page 8 of the datasheet...

http://ww1.microchip.com/downloads/en/DeviceDoc/39662e.pdf

And since you are new to hardware, my word of advice devote A LOT of time to reading the hardware datasheets for every component you use, it seems it's a human trait to not want to read 'instructions' and trust me it's a necessary evil in electronics...

There's a project in EPE magazine (check the EPE thread in the ebooks section) that uses the enc28j60 directly interfaced to a PIC to make a webserver. Might be worth a quick look.

It's in the December 2011 issue, and a few following that.
