Product Description

The TCA9800 is a dual-channel bidirectional buffer intended for I2C bus and SMBus/PMBus systems. It provides bidirectional level shifting (up-translation and down-translation) between low voltages (down to 0.8 V) and higher voltages (1.65 V to 3.6 V). The TCA9800 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 TCA9800 is able to 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 TCA9800 are very low (approximately 0.2 V), helping to eliminate communication issues as a result of fixed VIL thresholds. Another key feature of the TCA9800 is that there are 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 TCA9800 is used.
The TCA9800 is part of a four device family with varying current source strengths (see the _Device Comparison Table_).
