Description
The Texas Instruments TCA39306DTMR is a voltage-level translator for I2C bus and SMBus applications. It translates FM+ (Fast-mode Plus) I2C bus and SMBus voltage levels to ensure compatibility with devices operating at different supply voltages.
This device supports 12.5 MHz clock speed, various VREF2 options (1.8-V, 2.5-V, 3.3-V, or 5-V), and translates SDA and SCL lines for seamless communication between devices. It ensures I2C protocol compatibility, supporting fast-mode, standard-mode, and fast-mode plus modes.
The TCA39306DTMR is suitable for mixed-mode I2C applications, SMBus, and SMBus Plus protocols. Its fully compatible I2C protocols ensure reliable data transmission. This device is ideal for applications requiring voltage-level translation in a compact X2SON (DTM)-8 package.
