TCA9511A Hot-Swappable I2C Bus & SMBus Buffer
Texas Instruments TCA9511A Hot-Swappable I2C Bus and SMBus Buffer is a hot-swappable I2C bus buffer. The device supports I/O card insertion into an alive backplane without corruption of the data and clock buses. Control circuitry prevents the backplane-side I2C lines (in) from being connected to the card-side I2C lines (out) until a stop command or bus idle condition occurs on the backplane without bus contention on the card. The Texas Instruments TCA9511A provides bidirectional buffering when the connection is made, keeping the backplane and card capacitances separated. During insertion, the SDA and SCL lines are precharged to 1V to minimize the current required to charge the parasitic capacitance of the device.
