UCA9617 Overview
The UCA9617 enables I2C-bus or SMBus translation down to VCC(A) as low as 0.8V without degradation of system performance. The UCA9617 contains two bidirectional open-drain buffers specifically designed to support up-translation/down-translation between the low voltage (as low as 0.8V) and a 2.5V, 3.3V or 5V I2C-bus or SMBus. All inputs and I/Os are overvoltage tolerant to 5.5V even when the device is unpowered...
