TCA39416 Overview
Key Specifications
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 applications
- Provides bidirectional voltage translation with no direction pin
- High-impedance output Ax and Bx pins when OE = 0 V or VCC = 0 V
- Internal 10-kΩ pull-up resistor on Ax and Bx pins
- 0.72 V to 1.98 V on both A and B ports; VCCA ≤ VCCB
- Compatible with MIPI I3C supporting speeds up to 12.5 MHz
- Compatible with JEDEC I3C module sideband bus specification (JESD403)
- VCC Isolation feature: If either VCC input is at GND, both A and B ports are in the high-impedance state
- No power-supply sequencing required: either VCCA or VCCB can be ramped first
- Low Ioff of 2.5 µA when either VCCA or VCCB = 0 V
