The TCA9802DGKT from Texas Instruments is a dual-channel, bidirectional buffer designed for I2C and SMBus systems. It provides level translation between low voltages, down to 0.8 V on the A-side, and higher voltages from 1.65 V to 3.6 V on the B-side.
This buffer/repeater supports a maximum frequency of 400 kHz and features an active-high enable input. It is compatible with I2C bus and SMBus protocols, supporting clock stretching and multiple master arbitration. The device includes an integrated current source on the B-side, eliminating the need for external resistors.
Packaged in an 8-VSSOP, the TCA9802DGKT is suitable for surface mount applications. Its operating temperature range is -40°C to 125°C. The device offers ultra-low power consumption and no static-voltage offset.
Key features include bidirectional translation, support for multiple voltage domains, and powered-off high impedance I2C bus pins for system flexibility.
