Hi,
Refering to PIC18F2620 datasheet, section 26.3 on DC characteristics, it says that the input high voltage is only 2V for VDD between 4.5V and 5.5V.
BTW I am doing a project using PIC18F2620 and ENC28J60 and i was wondering, if the input high voltage is only 2V, then why would i still need additional CMOS chip to act as voltage level translator/shifter for ENC28J60's output pin SO, CLKOUT and INT. I mean, shouldn't the output voltage of 3.3V be sufficient to change the PIC pin from a LOW state to a HIGH state..?
Any thoughts..
Thanks..
