Texas Instruments TCA39416 I3C Translator

Texas Instruments TCA39416 I3C Translator is a 2-bit bidirectional MIPI I3C v1.1.1, I2C, SMBus, and SPI voltage-level translator with an Output Enable (OE) input and accelerator. This translator is a directionless voltage-level translator specifically designed for translating logic voltage levels. The TCA39416 translator is compatible with 12.5MHz I3C speeds and supports high-speed SPI applications with two devices. This device operates from 0.72V to 1.98V on both the A-side and B-side, with VCCA must be less than VCCB for proper operation. Features include internal 10kΩ pull-up resistors on Ax and Bx that act as high-keeper. The TCA39416 translator architecture is an auto-direction-sensing-based translator and is suitable for servers, wearables, and personal electronics.

Features

  • 2-bit dual supply bidirectional translator for I3C, I2C, SMBus, and SPI applications
  • Provides bidirectional voltage translation with no direction pin
  • High-impedance output Ax and Bx pins when OE = 0V or VCC = 0V
  • Internal 10kΩ pull-up resistor on Ax and Bx pins
  • 0.72V to 1.98V voltage range on both A and B ports, VCCA ≤ VCCB
  • Compatible with MIPI I3C supporting speeds up to 12.5MHz
  • VCC isolation features if either VCC input is at GND, both A and B ports are in the high-impedance state
  • No power-supply sequencing is required either VCCA or VCCB can be ramped first
  • Low Ioff of 2.5µA when either VCCA or VCCB = 0V
  • Operates from -40°C to 125°C temperature range
  • OE input can be tied directly to VCCA or controlled by GPIO
  • Latch-up performance exceeds 100mA per JESD 78, class II
  • ESD Protection exceeds JESD 22
    • 4000V Human-body model (A114-B)
    • 1500V Charged-device model (C101)

Applications

  • Servers
