TCA9406DCTR Description

Short technical summary and product information.

The TCA9406DCTR from Texas Instruments is a 2-bit bidirectional voltage level translator. It is designed to translate voltage levels between I2C and SMBus interfaces, facilitating communication between devices operating at different voltage rails.

 

This translator operates with a VCCA range of 1.65 V to 3.6 V and a VCCB range of 2.3 V to 5.5 V, ensuring compatibility with a wide array of system voltages. It supports bidirectional translation for both SDA and SCL lines without requiring a direction pin. The device features auto-direction sensing and an open-drain output type.

 

With a maximum operating frequency of 1 MHz, the TCA9406DCTR is suitable for many low-speed communication needs. It is available in a compact SM8 package, specifically an 8-LSSOP or 8-MSOP, and is designed for surface mount installation. The operating temperature range is -40°C to 85°C (TA).
