Max voltage output of DS18B20

[yamadanao614]

I am using the DigiX board and trying to connect a DS18B20 (one wire temperature sensor).

One of the issues with the DigiX is that it can only tolerate 3.3V on the I/O pins.

Here is the datesheet of ds18b20:http://www.componentschip.com/pdf/6a-DS18B20-T-R.pdf



I have been trying to look through the data sheet to try and find out what the max output could be.

Which, if I was powering with 3.3V would be too much? 3.3V +0.3V.

Is this the correct way to asses if there compatible and that I do in fact need a level shifter of some sort?

Thanks for your help, I just feel im missing something and it should be fine but I don't want to fry my board.

edit- I'm aware I could try measuring it with a multimeter but do not have access to one for a while and would not be confident in when or how t produce the max output current.

It says there in the spec sheet that it can tolerate a maximum of +6V.

Most embedded devices work on 5V, +/- some small tolerance. All electronic circuit boards have to operate on some voltage tolerance.

This is simply because the things you plug in to it affect the amount of voltage running through it.

Don't design to work on maximum tolerances. 3.3V is well within specs.

Hope this helps.
