Long Distance I2C Bus Extender

  • Extends I2C Communications to Minimum of 100 Feet
  • Includes Transmitter and Receiver Pair
  • Input Voltage Range 7.5V-35V
  • Compatible with 100KHz and 400KHz I2C Signals
  • 10x Improvement in Capactive Bus Handling


The P82B715TD I2C Range Extender Signal Conditioner is designed to extend the effective range of the I2C Bus from a few feet to a guaranteed minimum of 100 ft when using compatible cable* with a maximum operating speed of 400KHz.

We ship a Transmitter and Receiver together as a pair and 2 I2C Cables. You will only need CAT3 or better cable up to 100 Feet. The P82B715TD offers superior 10x capacitive handling of I2C signals for true bi-directional I2C communication applications. Compatible with I2C, SMBus, and other open-collector derivative protocols.

Cabling should not be installed near high-voltage power lines.

*Cable not included
