TCA9617BDGKR Description

Short technical summary and product information.

The TCA9617BDGKR from Texas Instruments is a dual bidirectional buffer designed for I2C and SMBus communication. This device facilitates voltage-level translation between systems operating at different voltage levels, supporting a wide range from 0.8V to 5.5V on the A-side and 2.2V to 5.5V on the B-side.

 

It operates at frequencies up to 1MHz, supporting standard, fast, and fast-mode+ I2C operations. The buffer features open-drain I/O and an active-high repeater-enable input. The TCA9617BDGKR is designed for lockup-free operation and offers powered-off high-impedance I2C bus pins for enhanced system management.

 

Packaged in an 8-VSSOP, this surface-mount device is suitable for various applications requiring robust I2C bus extension and level shifting. It provides essential ESD protection, rated up to 4000V for the human-body model and 1500V for the charged-device model.
