All of those comparator outputs should be a high state which means the LED will turn on connected through the 1K resistor to Vcc. The output is correct as seen on the scope.

Attached is a Multisim file with every comparator with a strobe feature available in Multisim and a picture of the ml311n. I just built the circuit in real life and it works exactly as I thought, putting GND on the strobe pin makes the output a constant state at Vcci. Message 5 of 5.

Message 3 of 5. You can note that the Output voltage stays high when pin 2 has higher voltage than pin 7 and vice versa. The transistor can also make the Load to be isolated from the system ground, so if you are looking for a Voltage comparator to drive loads of these specifications then this IC might be the right choice for you.

If the voltage at the Non-Inverting Terminal pin 2 is higher than the Inverting Terminal pin 2the output pin 7 will also be high datassheet the output will be low. Submitted by admin on 6 March When not in use the pins 5 and 6 should be shorted as shown above. A sample circuit is shown below in which the Inverting Terminal is set to 2.

The problem is that tying the strobe pin to ground should make the ,m311n stop changing, and it isn’t. I expect the output to oscillate between fatasheet and 1 at the “zero crossing” of the signal.

Could the component model be the issue? The simplified schematics of the IC is shown below: I built a simple circuit using the LMN comparator. The problem is that the strobe pin is not working for the model.

Message 2 of 5. Why is it not working in Multisim?

You can refer the other possible circuits from the LM datasheet given at bottom. Most Active Software Boards: Normally these pins are not used since the Input Offset itself is much better controlled. The LM can work on a Single supply voltage or in a dual supply mode.

According to the datasheet, if you tie the strobe datashwet to GND then the output should be disabled. Message 1 of 5. An Emitter Output Circuit is shown below.

As grounding unused pins is a practice on electronics, I guess it was the way of the designer to make sure the device was not disabled for a ground wired to that pin. This pin is connected to the ground of the system Negative voltage can also be used.

Any Op-Amp can be made to work as a voltage comparator, but the LM proves itself to be advantages by housing an Output Transistor inside its package.
