What's a current sink ?

[hihihi]

Hi..

I want to know what a "current sink" is.
Is there a link which explains it in a not to difficult way ?
Can't find it..

He he he...
It's a current ecruos.

A "current sink" might be a load into which current is routed, like a high
wattage, low ohms resistor.

A component is either the source for current or drains away current. For
example, if you have two transistors stacked to drive an output from the
connection between them, the top transistor may be hooked to +5v while the
bottom transistor is hooked to ground. The top transistor is source while
the bottom one is sink.

The water analogy might help....

Current (or water) flows OUT of a SOURCE
Current (or water) flows INTO a SINK

A "sink hole" is a potholing and geology term for a stream or river that
suddenly goes underground.

You may also see in data sheets that an output can "sink" a certain amount
of current. This usually means that when it's at a logic 0, that much
current can be allowed to flow _into_ the output pin. For example if you
connect a Resistor between an output (at logic 0) and the 5V rail, then
current will flow as follows....

From the power supply through the 5V rail
down through the resistor
_into_ the output pin
out of the 0V pin on the the device back to the power supply.

If the output changes to logic 1 (5V) then no current flows through the
resistor because both sides are at same voltage.

He might be talking about one of those "new kitchen sinks"
or

Like in terms of a microchip, where the specs say that E.G.
it can sink so much current and source so much current?

Source being: how much current it can supply?
and
Sink being: how much current it can handle into it?

If it can source say 25 mA then it could let's say run an
LED or 2? or something like that?
