The Texas Instruments TCA9517DR is a 2-bit, level-translating buffer/repeater designed for I2C and SMBus applications. It operates at frequencies up to 400kHz and supports a wide supply voltage range from 0.9V to 5.5V on the A-side and 2.7V to 5.5V on the B-side.
This device facilitates voltage-level translation, enabling communication between systems operating at different voltage levels, specifically from 0.9V-5.5V to 2.7V-5.5V. It features an open-drain output type and is compatible with both Standard Mode and Fast Mode I2C devices, accommodating multiple masters.
The TCA9517DR is available in an 8-SOIC package, suitable for surface mount applications. It operates within an ambient temperature range of -40°C to 85°C. The device also includes an active-high repeater-enable input and provides high-impedance I2C pins when powered off, enhancing system flexibility and power management.
Key electrical characteristics include ESD protection exceeding 5500V (HBM), latch-up performance greater than 100mA, and bidirectional buffering for two channels. This makes it a robust solution for extending I2C bus lengths or interfacing between different voltage domains in complex electronic systems.
