Hello,
Trying to use the NI-USB-8451 and Labview 2010.
The 8451 device has option for pull-up resistors (I2C bus) up to 3.3V.
Are the I2C SCL and SDA pins 5V tolerant?
Thank you

the appendix at the end of the manual states
"Absolute voltage range ...........................–0.5 to +5.8 V with respect to
GND" pg A3
