A source driver applies voltage to a ground (common)-referenced load. A sink driver grounds one side of a load which is already connected to the supply voltage. Given the same family of drivers, sink drivers generally have the greater current drive capability of the two.

What is the difference between upstream and downstream in electrical network?
Generally upstream is closer to the positive (+) voltage source. In the case of an NPN transistor upstream of the transistor is the part of the circuit from (+) to the NPN collector pin. Downstream of the transistor is from the NPN emitter pin to the ground / sink / negative (-) terminal.
Why there is no driver circuit needed between 8051 microcontroller and an optoisolater?
Are you referring to the original Intel 8051, or one of the many variants? The 8051 has weak internal pullups on the i/o pins, and can source only about 60 ua, but can sink 1.6 ma, still not much when it comes to driving the led in an opto. Some 8051-based dervatives can sink much more current. Atmel's 89C2051 for instance, can sink up to 20 ma per i/o pin. This can directly drive most optos.
How far is the required distance between electrical outlet and sink in an office building?
Before the code requiring all outlets to have GFCI protection that at within 6' of a water source you were required to install the outlet at least 6' from the sink. Now, there is no minimum distance but all outlets must be GFCI protected that are installed within 6' of a water source.
What is the standard distance between the ceiling and a wall mounted light fixture in a bathroom?
The height is usually based on the type of mirror that is to be installed above the sink. Take the height of the sink plus the height of the mirror and add 6 inches to find the center for the placement of the fixture junction box. If there is to be a space between the sink and the mirror add that measurement in to factoring of the height.
What is the difference between flow control and congestion control?
Flow control vs. congestion control: Flow control means preventing the source from sending data that the sink will end up dropping because it runs out of buffer space. This is fairly easy with a sliding window protocol--just make sure the source's window is no larger than the free space in the sink's buffer. TCP does this by letting the sink advertise its free buffer space in the window field of the acks. Congestion control means preventing (or trying to prevent) the source from sending data that will end up getting dropped by a router because its queue is full. This is more complicated, because packets from different sources travelling different paths can converge on the same queue.
The driving force for the movement of materials in the phloem of plants is what?
a difference in osmotic water potential between the source and the sink
Is sink node source or destination?
sink node is source
How many ways does heat transfer occur?
conduction - requires direct physical contact between source and sinkconvection - requires a fluid between source and sinkradiation - electromagnetic radiation from source to sink
What is the difference between a console sink and a normal sink?
To best differentiate the two look at the nut nozzle on the exterior platform of the sink. If it is wide then it is console and if it is narrow it must then be normal.
What is the difference between a washroom and a bathroom?
Generally, a washroom has a sink and toilet. A bathroom has a sink, toilet and tub. But the words are often used interchangeably.
What is the difference between restroom and bathroom?
rest room: toilet and a sink bathroom: toilet, sink and a shower or a bathing tub sometimes both
What is difference between sink node and base station in WSN?
A WSN typically consists of a sink node sometimes referred to as a Base Station
What is the difference between an atmospheric belt and an atmospheric zone?
belts sink and zones rise
What is the difference between a Boston Whaler and a Light patrol Boat?
A Boston Whaler can not sink
What is Sink and source mode of transistor?
Source mode at output provides safety than sink at output
Is the printer data source or data sink?
data sink
What is the difference between drown and sink?
drowning is death from suffocating under water, to sink is merely to go below the waters surface, anything can sink, only living things can drown.yeah that's what it is .
