Hi guys.
planing to connect due with 5 attiny85. Due is 3.3v and attiny85 run on 5v.
i want to use nxp P82B715 i2c range extender which his min voltage is 4.5v (this is why i decide to run tinys 5v.)
Is it going to be enough if i use BIDIRECTIONAL LEVEL SHIFTER to drive i2c bus btw those 5v tinys abd 3.3v due?
Or is due SDA,SCL lines 5v tolerant?
if any one have some design advice please fell free to post.
thanks for any help.
