★ ★ ★ ★ ★

When considering an output from an integrated circuit, source vs sink is very simply a matter of whether the current comes out of the pin (source) or goes into it (sinks). You often find NPN devices connected emitter to ground, and indeed configured to sink current when producing a logic low.

Open collector - Wikipedia

★ ★ ★ ★ ★

An open collector is a common type of output found on many integrated circuits (IC), which behaves like a switch that is either connected to ground or disconnected.. Instead of outputting a signal of a specific voltage or current, the output signal is applied to the base of an internal NPN transistor whose collector is externalized (open) on a pin of the IC.

0-10VDC Sinking Voltage output | All About Circuits

★ ★ ★ ★ ☆

8/23/2017 · I understand that most LED lighting inverters which allow for a 0-10VDC signal input to control the brightness require a voltage signal that can "sink" as opposed to a sourcing 0-10VDC output that most building controls provide. I need to covert a 0-10VDC sourcing output to a 0-10VDC sinking output in order to control these lights.

Here, the optocoupler LED and current-limiting resistor R1 are connected between the 5V positive supply rail and the output-driving terminal of the TTL device (rather than between the TTL output and ground), because TTL outputs can usually sink a fairly high current (typically 16mA) but can source only a very low current (typically 400µA).

So, where with most digital electronics, the output of a buffer (or other logic gate) is a “high” or “low” voltage, an open collector has two different states: Output transistor disabled or output transistor enabled. In other words, output (effectively) “not connected” or output connected, through a transistor, to ground.

4/16/2012 · Transistor as switch for application with mA only, larger current will create heat. When to use a MOSFET? If I need to SINK very large current say, 1000mA or 5000mA, then I use Mosfet because low heat lost. opto isolator as a switch? When I need to isolate input/output ground to system ground.
