    Is it safe to just down shift output pins on 5v SRAM?

    Thanks for your answer! I'll report back when the logic shifters come in.
  2. If I understand correctly the input pins on the Papilio One are not 5v safe and I should convert any input into the Papilio to 3v3. I only have SRAM modules that output 5v and use a 5v power supply but can read logic at 3v3 (which the Papilio outputs). Is it safe to just downshift the output pins on the SRAM from 5v to 3v3 and connect the address and control pins directly to the Papilio?
