TCA9517DGKRQ1 Description

Short technical summary and product information.

The TCA9517DGKRQ1 from Texas Instruments is an automotive-qualified, 2-bit bidirectional buffer/repeater designed for I2C and SMBus communication.

 

This device facilitates voltage-level translation, supporting a wide operating supply voltage range from 0.9V to 5.25V on the A-side and 2.7V to 5.25V on the B-side. It is capable of handling standard mode and fast mode I2C devices, making it suitable for systems with multiple controllers. The buffer operates at a maximum frequency of 400kHz.

 

Key features include an active-high repeater-enable input and open-drain I2C I/O. The device also offers 5.25V tolerant inputs, supporting mixed-mode signal operation. When powered off, the I2C pins enter a high-impedance state. The TCA9517DGKRQ1 is AEC-Q100 qualified for automotive applications and operates within a temperature range of -40°C to 125°C.

 

Packaged in an 8-VSSOP, the TCA9517DGKRQ1 is designed for surface mounting. Its latch-up performance exceeds 100 mA per JESD 78, class II.
