PI6ULS5V9617AUEX

The PI6ULS5V9617AUEX from Diodes Incorporated is a CMOS integrated circuit designed for Fast-mode Plus (Fm+) I2C-bus or SMBus applications. This 2-channel buffer provides bidirectional buffering for both data (SDA) and clock (SCL) lines, enabling voltage level translation between 0.6V and 5.5V. It effectively isolates capacitance on the bus, allowing for up to 540pF at 1 MHz or 4000pF at lower speeds.

Key features include a clock frequency range of 0 Hz to 1 MHz, 5V tolerant I2C-bus and enable pins, and open-drain input/outputs. The device supports arbitration and clock stretching across the repeater, accommodating Standard-mode, Fast-mode, and Fast-mode Plus I2C-bus devices, as well as SMBus and PMBus. The PI6ULS5V9617AUEX is available in an 8-MSOP package and operates within a temperature range of -40°C to 85°C.

This repeater is suitable for mixed-mode applications where systems require interfacing between low-voltage logic (down to 0.6V) and higher-voltage buses (2.2V to 5.5V). Its design helps extend I2C-bus trace lengths and accommodate more devices by isolating bus segments. The device is also RoHS3 compliant and considered a "Green" device, being Halogen and Antimony Free.
