PCA9306-Q1: Schematic Review

Part Number: PCA9306-Q1
Other Parts Discussed in Thread: PCA9306, USB2ANY

Hi Team,

I am trying to interface a USB2ANY device to an IC that has 1.8V logic. The USB2ANY device has 3.3V logic. Therefore, I am using the PCA9306 to translate between the two devices.

Can you please review the schematic below? VDD is 1.8V

Thank you!

Hey Jared,

Pin 7 and pin 8 of the device are not properly connected for the level translation configuration of the device. Pin 7 and 8 should be shorted together and the 200k resistor should come between Vref2 and the 3.3V rail.

Thanks,

-Bobby
