Description 8-channel Bi-directional Logic Level Converter - TXB0108
Most microcontrollers & Arduinos are 5V devices. Most modern sensors, displays and accessories are all 3.3V. It is therefore wise to perform a conversion to protect the 3.3V device from 5V. That is why Adafruit has developed this 8-channel level converter.
You can use this breakout to do bi-directional level shifting, from any voltage to any voltage . It detects the direction automatically. The breakout does not work well with I2C because it uses strong pullups. This confuses the auto-direction sensor. If you want to use pullups, they should be at least 50K Ohms.
Because this chip is a special bidirectional level shifter it does not have strong output pins . You cannot drive LEDs or long cables with it. The breakout is meant to be placed on a breadboard between two logic chips. If you do not need instant bidirectional support the 74LVC245 is a better choice . It offers a strong output.
Thanks to this breakout you don't have to solder small pitch chips. You do have to solder the supplied headers if you want to use the breakout on a breadboard . There are 0.1uF capacitors and a 10K pull-up resistor on the output enable pin. So you can use it right away.
