cmos current characteristics

[velu.plg]

i want the meaning of below quotes.

if drain current is positively increase at the same time source current is increases in negative manner.

hi,
Often the terms 'negative and positive' current are used to indicate whether the current is flowing into a device or out of the device, not the polarity of the current.

EDIT: look at this clip from a CMOS datasheet, note the '-' sign on the High level output current

Which manufacturer is afraid to use the English words Source (when its output is high) and Sink (when its output is low) on its datasheets?

Texas Instruments speeky zee English very well on their datasheets for Cmos ICs and says Source and Sink. They have the usual printed text spec's for output current with 5V, 10V and 15V supplies but also have minimum and typical output current on graphs that show variable supply voltages and variable load voltages. I use these graphs to see the current in an LED that does not have a series current-limiting resistor.
