Key Features
- Bidirectional voltage level translation between 1.0 V and 5 V I2C bus segments
- Open-drain SDA/SCL outputs with rail isolation for safe mixed-voltage operation
- Maximum 230 ns propagation delay supports Standard-Mode and Fast-Mode (400 kHz) I2C
- Compact SOIC-8 (R-PDSO-G8) surface-mount package, RoHS and Pb-free compliant
- Drop-in upgrade path for legacy PCA9517 / TCA9517A designs requiring tighter timing
Applications
Designed for mixed-voltage I2C systems where a 1.8 V or 3.3 V MCU communicates with 5 V peripherals such as EEPROMs, RTCs, sensors, and PMICs. Common in industrial control boards, automotive infotainment modules, smart-meter front ends, and consumer IoT devices that consolidate multiple bus voltages onto a single I2C trunk.

Frequently Asked Questions
What voltage rails does the TCA9517DR translate between?
The TCA9517DR translates bidirectionally between any two I2C bus voltages from 1.0 V on the lower side up to 5 V on the higher side, making it ideal for connecting 1.8 V or 3.3 V MCUs to 5 V peripherals.
What I2C bus speeds does the TCA9517DR support?
With a maximum propagation delay of 230 ns, the TCA9517DR comfortably supports Standard-Mode (100 kHz) and Fast-Mode (400 kHz) I2C operation, and can drive Fast-Mode Plus buses with conservative pull-up sizing and short trace lengths.
What package is the TCA9517DR available in, and is it RoHS compliant?
The TCA9517DR ships in a SOIC-8 (R-PDSO-G8) surface-mount package. It is fully RoHS compliant and lead-free per TI's Pb-Free standards, suitable for both standard and lead-free reflow assembly profiles.
Is the TCA9517DR pin-compatible with other TI I2C level translators?
Yes, the TCA9517DR is pin-compatible with the TCA9517A and similar 2-bit I2C bus repeaters in the SOIC-8 footprint, enabling drop-in replacement when tighter timing or different drive strengths are required.
