TCA4311A Hot Swappable 2-Wire Bus Buffers

The TCA4311A is a hot-swappable I2C bus buffer that supports I/O card insertion into a live backplane without corruption of the data and clock busses. Control circuitry prevents the backplane from being connected to the card until a stop command or bus idle occurs on the backplane without bus conten.

TCA4311A Features

* 1 Operating Power-Supply Voltage Range of 2.7 V to 5.5 V

* Supports Bidirectional Data Transfer of I2C Bus Signals

* SDA and SCL Lines are Buffered Which Increases Fanout

* 1-V Precharge on all SDA and SCL Lines Prevents Corruption During Live Board Insertion and Rem
