Adafruit 4-Bit Level Converter


This Adafruit 4-Bit Level Converter has 4 BSS138 FETs with 10K pullups. It works down to 1.8V on the low side, and up to 10V on the high side.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 converter was designed to be used with I2C, but also works great for SPI, TTL Serial, and any other digital interface both uni-directional and bidirectional!

*Just an FYI, the 10K's do make the interface a little more sluggish than using a TXB0108 or 74LVC245.
