TCA39416 - Ultra-Low-Voltage I3C Translator

General Description

The TCA39416 is a 2-bit bidirectional MIPI I3C v1.1.1, I2C, 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 VCCA must be less than VCCB for proper operation.

Key Features

  • 2-bit dual supply bidirectional translator for I3C, I2C, SMBus, SPI.
