Product Description:
The TCA4311A is a hot-swappable I 2C 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. When the connection is made, this device provides bidirectional buffering, keeping the backplane and card capacitances isolated. During insertion, the SDA and SCL lines are pre-charged to 1 V to minimize the current required to charge the parasitic capacitance of the chip. When the I 2C bus is idle, the TCA4311A can be put into shutdown mode by setting the EN pin low. When EN is high, the TCA4311A resumes normal operation. It also includes an open drain READY output pin, which indicates that the backplane and card sides are connected together. When READY is high, the SDAIN and SCLIN are connected to SDAOUT and SCLOUT. When the two sides are disconnected, READY is low. Both the backplane and card may be powered with supply voltages ranging from 2.7 V to 5.5 V, with no restrictions on which supply voltage is higher. The TCA4311A has standard open-drain I/Os. The size of the pull-up resistors to the I/Os depends on the system, but each side of this buffer must have a pull-up resistor. The device is designed to work with Standard Mode and Fast Mode I 2C devices in addition to SMBus devices. Standard Mode I 2C devices only specify 3 mA in a generic I 2C system where Standard Mode devices and multiple masters are possible. Under certain conditions, high termination currents can be used.
