TCA4311 Datasheet (Texas Instruments) - Hot Swappable 2-Wire Bus Buffers

TCA4311, Hot Swappable 2-Wire Bus Buffers

The TCA4311 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 content

TCA4311 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
