Part Number: LM311 Hello team,
On the datasheet, Abs max value of EMIT OUT and COL OUT is not related to VCC. Is this mean that, even during VCC=0V, those pins can withstand up to 30V and 40V respectively?

Part Number: LM311 Hi I will like to suggest a new quad comparator device (sorry if this isn’t the right place for this). The LM311 comparator has been around for many years, but still seems very popular because of some unique features, like ±15V…

Hello,
We bought from you LM311 and how can I recognize where pin number 1 is? In datasheet there is a dot or notch in the housing, but on these on picture there is not.
Best regards,

Part Number: LM311 Hi Experts,
Our customer is trying to simulate the following LM311 circuit with hysteresis in LTspice:
The circuit is supposed to be a comparator with hysteresis centered around 2.5V, with high threshold 3.1V and low threshold 1.9V. …
Part Number: LM311 Other Parts Discussed in Thread: TINA-TI Dear sir, please answer
I need to set a hysteresis in LM311. Please, report, should I connect the feedback resistor between pins “COL” and “+IN” or between pins “COL” and “-IN” ?…

Hello,
I would like to build a bipolar window comparator with hysteresis. The input signal is a sinus waveform, 5 Hz and 8 V peak. Here is my simulation:
The simulation is not working…
Part Number: LM311 Other Parts Discussed in Thread: LM2903 Hi Team:
My customer want to use LM311 to capture 13V pulsed quadrature signal for MCU to detect high / low .
If the ref voltage for LM311 is 6.5V, does it work with single power supply 15V? The…
Part Number: LM311-N Other Parts Discussed in Thread: LM311 , TLV1812-Q1 Hello guys,
One of my customers is considering using LM311M(X)/NOPB. They have the following questions. Could you please tell me your reply?
Q1. What is LM311-N minimum operation v…
Part Number: LM311 Hello team,
I received a question from the customer as follows,
[Issue]
When the frequency of the input signal exceeds 180 kHz, the comparator operates even though it is below the threshold(Only Hi side).
