Abstract
A bus repeater with voltage conversion and multiplexing circuits for use between devices with incompatible voltage levels communicating over inter-integrated circuit (I2C) buses. Bi-directional data and clock lines are passed through the circuit from one bus to the other, blocked so they are not passed on, or modified before being passed on, depending on the current transaction. The repeater is placed between two separate I2C buses and communicates between the two buses. To accommodate the slow-slave requirements of an I2C bus, the duration of signals on the clock line may be modified.
