- AEC-Q100 automotive qualification covers -40°C to 125°C operation, making it suitable for in-vehicle infotainment, ADAS, and body-control communication buses
- Wide voltage range translation between 1.0 V and 5.5 V allows interfacing of mixed-voltage I2C buses in multi-rail automotive SoC and sensor designs
Applications
TCA39306DCURQ1 is used in automotive electronic control units to bridge I2C and SMBus communication between microcontrollers and sensors or EEPROMs operating at different supply voltages. It is ideal in ADAS camera modules, infotainment systems, and body control modules where 1.8 V processors must communicate with legacy 3.3 V or 5 V peripherals over I2C. Its AEC-Q100 qualification ensures long-term reliability in high-vibration, wide-temperature automotive environments.

Frequently Asked Questions
What I2C bus speeds does TCA39306DCURQ1 support, and what is its maximum propagation delay?
TCA39306DCURQ1 supports Standard-mode (100 kHz), Fast-mode (400 kHz), and FM+ (1 MHz) I2C bus speeds. Its maximum propagation delay is 46 ns, which is well within the timing budget for FM+ operation, allowing reliable high-speed translation between mixed-voltage I2C buses in automotive ECUs.
Which voltage rails can TCA39306DCURQ1 translate between in a mixed-supply automotive SoC design?
TCA39306DCURQ1 translates between any two voltage levels from 1.0 V to 5.5 V, covering common automotive rails such as 1.2 V, 1.8 V, 3.3 V, and 5 V. This enables a 1.8 V automotive SoC to communicate over I2C with a 5 V sensor or EEPROM without any additional discrete components.
For a compact automotive sensor hub, how many I2C bits does TCA39306DCURQ1 translate and what package size does it use?
TCA39306DCURQ1 provides 2-bit bidirectional voltage-level translation covering SDA and SCL lines of a single I2C bus. It is housed in an 8-pin VSSOP package, which offers a very small PCB footprint suitable for densely populated automotive sensor interface boards operating from -40°C to 125°C.
