TCA4311A
Overview
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 contention on the card.
- 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 Removal From Backplane
- SDA and SCL Input Lines are Isolated From Outputs
- Accommodates Standard Mode and Fast Mode I2C Devices
- Improved Noise Immunity
