TCA9802 I2C Bus Buffer/Repeater Texas Instruments TCA9802 I2C Bus Buffer/Repeater is a dual-channel bi-directional buffer for I2C bus and SMBus/PMBus systems. This device provides bi-directional level shifting (up-translation and down-translation) between low voltages (down to 0.8V) and higher voltages (1.65V to 3.6V). The TCA9802 features an internal current source on the B-side of the device, allowing the removal of external pull-up resistors on the B-side. The current source also provides an improved rise time and ultra-low power consumption. The TCA9802 can provide true buffering (rather than a pass-FET solution) without using a static voltage offset or incremental offset. This means that the VOL on both the A and B sides of the device is very low, helping to eliminate communication issues due to fixed VIL thresholds. Another key feature of the TCA9802 is no power sequencing requirements or power supply dependencies. VCCA can be greater than, less than, or equal to VCCB. This gives the system designer flexibility with how the TCA9802 is used.
