TCA4307DRGR Description

Short technical summary and product information.

The TCA4307DRGR from Texas Instruments is a hot-swappable I2C bus and SMBus buffer. This 2-bit bidirectional buffer supports I/O card insertion into a live backplane without corrupting data and clock lines.

 

It operates over a wide power-supply voltage range of 2.3V to 5.5V and supports a maximum frequency of 0.4MHz. The device features stuck bus recovery, automatic bus recovery, and 1-V precharge on SDA and SCL lines to prevent corruption during live insertion. It accommodates standard mode and fast mode I2C devices and supports clock stretching, arbitration, and synchronization.

 

The TCA4307DRGR is available in WSON (DRG) 8 and VSSOP (DGK) 8 packages. Its operating temperature range is -40°C to 125°C.

 

This buffer is suitable for applications requiring reliable I2C communication during hot-plug events, ensuring data integrity and system stability.
