TCA39306-Q1Automotive FM+ I²C bus and SMBus voltage translator | Translators, Level Shifters | 1 | Active | The TCA39306-Q1 is a dual bidirectional voltage-level translator compatible with I 2C, SMBus, and I 3C with an enable (EN) input, and is operational from 0.9-V to 3.3-V V REF1 and 1.8-V to 5.5-V V REF2.
The device allows bidirectional voltage translations between 0.85 V and 5 V, without the use of a direction pin. The low ON-state resistance (R ON) of the switch allows connections to be made with minimal propagation delay. When EN is high, the translator switch is ON, and the SCL1 and SDA1 I/O are connected to the SCL2 and SDA2 I/O, respectively, allowing bidirectional data flow between ports. When EN is low, the translator switch is off, and a high-impedance state exists between ports.
In addition to voltage translation, the TCA39306-Q1 can be used to isolate a higher speed bus from a lower speed bus by controlling the EN pin to disconnect the slower bus during fast-mode communication.

TCA39416Ultra-low-voltage I3C translator with rise time accelerators | Logic | 2 | Active | The TCA39416 is a 2-bit bidirectional MIPI I3C v1.1.1, I 2C, SMBus and SPI voltage-level translator with an output enable (OE) input and rising and falling edge accelerators. It is operational from 0.72 V to 1.98 V on both the A-side and B-side with V CCA must be less than V CCB for proper operation. This limitation allows the device to interface between lower and higher logic signal levels at any of the typical 1-V, 1.2-V and 1.8-V supply rails.
The OE input pin is referenced to V CCA, can be tied directly to V CCA, but it is also 1.98-V tolerant. The OE pin can also be controlled and set to a logic low to place all the Ax (A1, A2) and Bx (B1, B2) pins in a high-impedance state, which significantly reduces the quiescent current consumption.
The TCA39416 is compatible with 12.5 MHz I3C speeds and also supports higher speed SPI applications with two devices. It also enables bidirectional voltage level translation for traditional I2C-bus/SMBus applications under normal I 2C and SMBus configurations.
The TCA39416 features internal 10-kΩ pull-up resistors on Ax and Bx that act as high-keeper and are enabled based on respective V CC voltage when bus is high.

TCA43072-bit bidirectional 2.3-V to 5.5-V, hot-swappable 400-kHz I2C/SMBus buffer with stuck- | Power Management (PMIC) | 1 | Active | The TCA4307 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 lines. Control circuitry prevents the backplane-side I 2C lines (in) from being connected to the card-side I 2C lines (out) until a stop command or bus idle condition 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 capacitance 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 device.
The TCA4307 has stuck bus recovery, which automatically disconnects the bus if it detects either SDAOUT or SCLOUT are low for about 40 ms. Once the bus is disconnected, the device automatically generates up to 16 pulses on SCLOUT to attempt to reset the device which is holding the bus low.
When the I 2C bus is idle, the TCA4307 can be put into shutdown mode by setting the EN pin low, reducing power consumption. When EN is pulled high, the TCA4307 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.
