TCA4311A Description

Product Folder Order Now Technical Documents Tools & Software Support & Community TCA4311A SCPS226C * JANUARY 2011 * REVISED AUGU.
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.

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

TCA4311A Applications

* Include Hot Board Insertion and Bus Extension
* Low ICC Chip Disable of < 1 μA
* READY Open-Drain Output
* Supports Clock Stretching, Arbitration, and Synchronization
* Powered-Off High-Impedance I2C Pins
* Open-Drain I2C Pins
* Latch-Up Performance Ex
