2238: add spec on max voltage with term
Updates #35. Same termination structure as bnc/sma-ttl card. Technically the max allowable voltage with termination is a bit higher than 5V. But it seems that it will still exceed the termination resistor rating limit at 5.5V. The only method of acquiring V_ds & other parameters is by eye-balling the I-V curve of the MOSFET, which is not precise. So the calculation assumes V_ds=0, just to be conservative.
