The source current is the current provided by the component when the output pin of that component is high. The source current can reveal fanout capability. Fanout means how many logic gates can be connected to the output of the gate being considered.Originally posted by Surendar@Jan 7 2006, 01:08 AM
What is Source current and what is sink current.
When an IC has open collector outputs, it means that each collector is not internally tied to the DC power supply. Therefore the user of that IC should provide external pullup resistors to the DC power supply. Without the external pullup resistor, when the logic inside the IC tries to generate a logic high, the open collector output pin will be floating.Originally posted by zhi_yi@Jan 26 2006, 09:13 AM
what is the meaning of open collector??
