Other Parts Discussed in Thread: LM2901V, LM239A, , LM139, LM139A, LM2901AV, LM239, LM2901,
The LM339 data sheet (SLCS006T) states (Section 8.3 Feature Description):
"The output NPN sinks current when the positive input voltage is higher than the negative input voltage and the offset voltage. "
Which is not typical of comparators and also disagrees with the description in 9.2.2.1.
It also disagrees with the Electrical Characteristics:
IOL Low-level output current is typically 16mA when VID=–1V (IN+ with respect to IN-).
Am I reading something wrong?
