DigitalIn maximum voltage?

Hi,

I need to read a digital sensor using the Digital In method, I know that parameters of what makes a 1 and a 0 are 2 and 0.8, but what is the maximum voltage that the mbed can handle on one of the inputs?

I think the sensor output will be roughly 10V at around 14mA, and will be at that value for a maximum of 3ms.

Will this be too high for the mbed?

Thanks.

The LPC mbeds have an absolute max of 5.5V, the KL25 of a bit above 3.3V. So yeah that won't be healthy.
