TCA9517ADGKR Description

Short technical summary and product information.

The TCA9517ADGKR from Texas Instruments is a versatile 2-bit bidirectional buffer and repeater designed for I2C and SMBus applications. This level-shifting IC facilitates voltage translation between 0.9V to 5.5V on the A-side and 2.7V to 5.5V on the B-side, supporting mixed-mode signal operation.

 

With a maximum frequency of 400kHz, the TCA9517ADGKR is suitable for standard mode and fast mode I2C devices. It features an active-high repeater-enable input and open-drain I2C I/O. The device also offers 5.5V tolerant inputs and powered-off high-impedance I2C pins for enhanced system flexibility.

 

Packaged in an 8-VSSOP, the TCA9517ADGKR is designed for surface mount applications. Its latch-up performance exceeds 100mA, and ESD protection meets JESD 22 standards, including 5500V for the human-body model. This component is a footprint and functional replacement for the PCA9515B.

 

Key electrical characteristics include a wide operating supply voltage range from 0.9V to 5.5V on VCCA and 2.7V to 5.5V on VCCB. The operating temperature range is -40°C to 85°C.
