8 Channel 8 Bit Logic Level Bi-directional Converter Module TXB0108 for Arduino
1,19 €
Its a little more luxurious than a 74LVX245 but if you just don't want to worry about directional pins this is a life saver! If you do not need instant bi-directional support, we suggest the 74LVX245 as below which has strong output drive.
