NXP Semiconductors PCA9507

The PCA9507 is a 2-wire serial bus extender providing 3.3 V to 5 V level shift that allows up to 18 meters bus extension for reliable DDC, I2C-bus or SMBus applications. The SDA and SCL pins are overvoltage tolerant and are high-impedance when the PCA9507 is unpowered. The port B drivers with static level offset behave much like the drivers on the PCA9515 device, while the port A drivers integrate the rise time accelerator, sink more current and eliminate the static offset voltage.
