The TCA9517-Q1 is a bidirectional buffer with level shifting capabilities for I2C and SMBus systems. It supplies bidirectional voltage-level translation (up-translation and/or down-translation) between low voltages (down to 0.9 V) and higher voltages (2.7 V to 5.25 V) in mixed-mode applications. This device enables I2C and SMBus systems to be extended without loss of performance, even during level shifting.

The TCA9517-Q1 buffers both the serial data (SDA) and the serial clock (SCL) signals on the I2C bus, thus allowing two buses of up to 400-pF bus capacitance to be connected in an I2C application.

The TCA9517-Q1 has two types of drivers: A-side drivers and B-side drivers. All inputs and I/Os are overvoltage tolerant to 5.25 V, even when the device is unpowered (VCCB and/or VCCA = 0 V).
