Addressable I²C bus buffer – what it does
The LTC4302IMS-1#PBF is an addressable 2-wire bus buffer and accelerator from Analog Devices, designed to isolate bus capacitance and allow hot-swap card insertion on an I²C bus without corrupting the clock or data lines. It operates at the standard I²C Fast-mode data rate of 400 kHz, supporting the majority of I²C peripherals without speed penalty. Two channels buffer both SDA and SCL lines independently, or can be used to buffer two separate I²C buses.
Supply range and temperature grade
The supply voltage range of 2.7V to 5.5V covers 3.3V and 5V I²C rails, common in mixed-voltage systems.
Active production – sourcing posture
