I2C & SMBus Bus Buffers & Accelerators

Analog Devices’ family of I2C devices address other digital serial 2-wire buses, including SMBus, PMBus, the ATCA intelligent platform management bus (IPMB), and the HDMI DDC bus. Our standalone or built-in rise time accelerators help speed up signal rise times to help meet I2C requirements, while our software-programmable and pin-selectable I2C multiplexers help resolve I2C address limitations, increase fan-in or fan-out, and integrate bus buffers and rise time accelerators for an all-in-one solution. Resistor configurable I2C address translators can be configured with over 100 unique slave addresses to allow multiple slave devices with the same address to coexist on the same bus. Our I2C bus buffers and multiplexers also provide automatic recovery from an I2C bus stuck low.
