What are the key features of PCA9306DP1,125?
- Dual-channel bidirectional I2C and SMBus translation between 1.2 V to 5.5 V logic domains
- Automatic direction sensing with no DIR control pin required — simplifies PCB design
- 3.3 ns maximum propagation delay supports standard and fast mode I2C up to 400 kHz
- Operates across -40°C to +125°C for automotive and industrial temperature environments
What is PCA9306DP1,125 used for?
The PCA9306DP1,125 is used in mixed-voltage embedded systems where a 3.3 V microcontroller must communicate over I2C with 1.8 V sensors, 5 V EEPROMs, or other peripherals at a different logic level. Its auto-direction sensing eliminates the need for control signals, making it a drop-in solution for SDA and SCL line translation in smartphones, IoT devices, and industrial sensor hubs. The compact 8-pin SOIC package keeps board area minimal in space-constrained designs.

Frequently Asked Questions
How does the PCA9306DP1,125 handle direction detection on bidirectional I2C lines without a DIR pin?
The PCA9306DP1,125 uses an open-drain FET topology that senses the dominant state on each SDA or SCL line. When one side pulls the line low, the transistor on the other side activates, propagating the signal in under 3.3 ns. This auto-direction approach requires no firmware control and supports 400 kHz fast-mode I2C correctly.
Which voltage rail combinations does the PCA9306DP1,125 support for translating between MCU and sensor logic levels?
The PCA9306DP1,125 accommodates any two independent voltage rails each between 1.2 V and 5.5 V on its VREF1 and VREF2 pins. Common combinations include 3.3 V MCU to 1.8 V sensor, 5 V legacy bus to 3.3 V processor, or 1.8 V application processor to 1.2 V DDR controller — all without additional bias components.
Is the PCA9306DP1,125 suitable for automotive infotainment systems that require AEC-Q100 qualified components?
The PCA9306DP1,125 is rated for operation from -40°C to +125°C, covering the AEC-Q100 Grade 1 temperature range required by automotive applications. It is suitable for CAN gateway, infotainment, and ADAS sensor interface boards where I2C voltage translation between 1.8 V and 3.3 V domains must be reliable across extreme temperatures.
