8-channel Bi-directional Logic Level Converter - TXB0108 (ID: 395) is backordered and will ship as soon as it is back in stock.


DESCRIPTION

Because the Arduino (and Basic Stamp) are 5V devices, and most modern sensors, displays, flash cards and modes are 3.3V-only, many makers find that they need to perform level shifting/conversion to protect the 3.3V device from 5V.

This chip performs bidirectional level shifting from pretty much any voltage to any voltage and will auto-detect the direction. The only thing that doesn't work well with this chip is i2c (because it uses strong pullups which confuse the auto-direction sensor). If you need to use pullups, you can but they should be at least 50K ohm - the ones internal to AVRs/Arduino are about 100K ohm. 0.1uF caps have also been added onto both sides and a 10K pull-up resistor on the output enable pin so you can use it right out of the box.
