TCA39416
- 2-bit dual supply bidirectional translator for I3C, I 2C, SMBus, SPI applications
- Provides bidirectional voltage translation with no direction pin
- High-impedance output Ax and Bx pins when OE = 0 V or V CC = 0 V

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.
