The TCA9617A is a BiCMOS dual bidirectional buffer intended for I2C bus and SMBus systems. The device provides bidirectional voltage-level translation (up-translation and down-translation) between low voltages (down to 0.8V) and higher voltages (2.2V to 5.5V) in mixed-mode applications. This device enables I2C and similar bus systems to be extended, without degradation of performance even during level shifting.

The TCA9617A buffers both the serial data (SDA) and the serial clock (SCL) signals on the I2C bus, allowing two buses of 550pF to be connected in an I2C application. This device can also be used to separate two halves of a bus for voltage and capacitance.
