Texas Instruments TCA9617BDGKR

The TCA9617B is a BiCMOS dual bidirectional buffer intended for I2C bus and SMBus systems. It can provide bidirectional voltage-level translation (up-translation and down-translation) between low voltages (down to 0.8 V) and higher voltages (2.2 V to 5.5 V) in mixed-mode applications. This device enables I2C and similar bus systems to be extended, without degradation of performance even during level shifting.

The TCA9617B buffers both the serial data (SDA) and the serial clock (SCL) signals on the I2C bus, allowing two buses of 550 pF to be connected in an I2C application. This device can also be used to isolate two halves of a bus for voltage and capacitance.
