That would be, with the far end of the resistor tied either to 5 volts or to ground, a half a milliamp current flow. I might start checking things at 10 mills or more, but some of the buffer chips in use today can source or sink 24 mills. Half a milliamp s/b a total non-issue. > > Dave Caroline > > ------------------------------------------------------------------------ > ------ For Developers, A Lot Can Happen In A Second. > Boundary is the first to Know...and Tell You. > Monitor Your Applications in Ultra-Fine Resolution.
