TCA9406YZPR Description

Short technical summary and product information.

The TCA9406YZPR from Texas Instruments is a 2-bit bidirectional voltage level translator suitable for interfacing between different logic levels in I2C and SMBus systems. It operates from 1.65V to 3.6V on the A-side and 2.3V to 5.5V on the B-side, accommodating common voltage rails like 1.8V, 2.5V, 3.3V, and 5V.

 

This translator features auto-direction sensing, eliminating the need for a direction pin, and provides an open-drain output. It supports data rates up to 24Mbps and includes internal 10kΩ pull-up resistors on all SDA and SCL lines. The device is designed for VCC isolation, ensuring high-impedance outputs when either VCC supply is at ground, and does not require specific power-supply sequencing.

 

Packaged in an 8-pin DSBGA (1.9x0.9 mm), the TCA9406YZPR is designed for surface mounting. It operates within a temperature range of -40°C to 85°C. The device offers robust ESD protection, exceeding JESD 22 standards for both A and B ports, with 8kV HBM protection on the B port.
