5V was placed on one of the data pins (D+ or D-) and no other power was supplied to the device. Would damage have occurred?
We have a board that uses the FX3 part (CYUSB3014-BZX) and is powered by the USB bus. The wiring harness had a mistake and 5V was placed on one of the data pins (D+ or D-). Since the board is powered by the USB bus, no other power rails were present to the FX3 part. I don't see any info in the datasheet about absolute levels on the USB pins.
I need the questioned answered urgently.
Thank you,
Jeff

Hello,
The maximum tolerant voltage for D+ and D- is 3.6V. As you have supplied a voltage of 5V, there is a high probability for the device to be damaged.

The FX3 is working as a USB device.
