The TCA9509DGKR from Texas Instruments is an integrated circuit designed as a 2-bit level-translating buffer and repeater for I2C and SMBus systems. This device enables the extension of I2C and similar bus systems without performance degradation, facilitating bidirectional voltage-level translation between low voltages down to 0.9V and higher voltages from 2.7V to 5.5V in mixed-mode applications.
Key features include compatibility with I2C and SMBus protocols, support for 400kHz fast mode operation, and an active-high repeater-enable input. It requires no external pullup resistors on the lower-voltage port-A and supports mixed-mode signal operation with 5.5V tolerant I2C and enable inputs. The device offers lockup-free operation and supports arbitration and clock stretching across the repeater.
Packaged in an 8-VSSOP, the TCA9509DGKR is suitable for surface mount applications. It operates within a temperature range of -40°C to 85°C and comes in a standard package quantity of 2,500 units on tape and reel.
