General Description

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 (VCC(B) and/or VCC(A)=0V).

Key Features

Footprint and functional replacement for UCA9617 at.
0Hz to 1000kHz clock frequency (the maximum system Fast-mode speeds operating frequency may be less than 1000kHz because.
2 channel, bidirectional buffer isolates capacitance and of the delays added by the repeater) allows 540pF on either side of the device at 1 MHz and.
Active HIGH repeater enable input referenced to VCC(B) up to 4000pF at lower speeds.
Open-drain input/outputs.
Voltage level translatio.
