I am using the LM139 comparator chip. Now, I understand that the output of the comparators,or for that matter op amps are open drain/collector. SO they can only sink current and not source it per se.
I had a glimps of the data sheet which says Iout = 20mAmps. Is it the max current that it can sink ?
Also, in the LT1716, the output pin is stated as - "The output stage of the LT1716 can drive loads connected to a supply more positive than the device, the same as comparators with open collector output stages.".
Does this mean it (output load) has to be connected to a different voltage rail. Suppose I connect the comp to 44V (Vcc), then effectively the Load should be connected to a voltage rail > 44V.
Are my assumptions right ?
