Part Number: LM339 About LM339 (and the other general purpose OPAMP), please let me confirm about datasheet information.
In the datasheet, pin assign: 8~11pin are different of page-4 and page-13. (IN+ and IN- are inverted)
Which is correct?

Hello Eduardo,
The LM339 does not have a "standby" mode, it has a continuous quiescent current draw. Current is typically about 200uA per comparator.
The supply current may increase a few percent as the output toggles faster - but is generally constant…
Hi Chaithra,
a 5MHz signal has a period of 200ns. As the switching times of the LM339 are longer than 200ns, the LM339 is not suited too handle 5MHz signals.

Part Number: LM339 I am using an LM339 in conjunction with a 4401 transistor to control a FET.
I have started to see a rash of FET failures and have been able to make the circuit work and/or fail by changing the LM339.
The part markings on all the…
Part Number: LM339 Hi,
As per data sheet of LM339, the input voltage range is from -0.3V to 36V. We are using LM339 as a Comparator in our circuit , in certain cases, we have a voltage of -0.7V at Vin ( inverting). which is above the specification…
Part Number: LM339 Hi
I have a simple question about common mode voltage range.
Is the following condition acceptable?
Vcc=5V, IN-=2V(Fixed), IN+=0.15~5V
IN+ is exceed the common-mode voltage range(0 to VCC-1.5V at 25degC). However it does…
Hello Shimizu,
For the LM339 family, yes, the output condition should be correct if *one* input is within common mode range.This is mentioned in table notes and the Apps section.
THIS IS NOT TRUE FOR ALL COMAPRATORS!
This is typical behavior of…
Part Number: LM311 Other Parts Discussed in Thread: LM339 , LM331 I have a need to detect signal polarity and shift this signal to a logic level. The signal input ranges from +/-12V and polarity detection is required to +/-100mv level. Logic level can…
