This is a useful circuit for straighforward logic level conversion so long as the 5V high side of the circuit can accept the limitations of a logic level of 3V for high. Each level converter has the capability of converting 4 pins on the high side to 4 pins on the low side. 3V-only, many makers find that they need to perform level shifting/conversion to protect the 3. 45V when high once or twice. Here, we have an Arduino UNO, an Accellerometer, a Compass, a Barometric Pressure Sensor, and a Raspberry PI all on the same I2C channel. 2 Configuration Level-Shift. VIN = 20 V, VON/OFF = 8 V, TA = 25 °C c. Level Shifters | Level Translators. The I2C-bus was introduced in 1980 by Philips Semiconductors and, in Application Note AN97055 they detail a simple bi-directional level-shifter for the I2C bus using two MOSFETS. TCA9509 Level Translating I²C Bus Repeater - TI | DigiKey. When used in conjunction with isolated power. 3V I2C bus lines of the MCU to a 2. One is the Arduino, at 5v. I would suggest you to stay with SIO at 5V. 3V HDMI DDC 5V Tol I2C DC 3. Production quantities are available now and the price is $4. 2K pull-up resistors on each bus line on both the 5V and 3. Their GU7000 Arduino library is easy to set up and use: it took just a couple of minutes to get out this message. 3K on the 3. This breakout has 4 BSS138 FETs with 10K pullups.
