The TCA9803DGKT from Texas Instruments is a 2-bit, level-translating I2C/SMBus buffer/repeater designed for bidirectional voltage translation. It supports operation with supply voltages ranging from 0.8V to 3.6V on the A-side and 1.65V to 3.6V on the B-side. This device is capable of translating between low voltages and higher voltages, facilitating communication in mixed-voltage systems.
Key features include a maximum frequency of 0.4 MHz, bidirectional channel type, and an active-high enable pin. The buffer incorporates an internal 3-mA current source on the B-side, eliminating the need for external resistors. It is compatible with I2C and SMBus protocols, supports clock stretching, and offers powered-off high impedance on I2C bus pins for protection.
Packaged in an 8-VSSOP, the TCA9803DGKT is suitable for surface mount applications. Its operating temperature range is -40°C to 125°C (TA). This component is ideal for systems requiring reliable level shifting and buffering for I2C and SMBus communication lines, particularly in applications with varying voltage domains.
