LM393 is a dual voltage comparator integrated circuit. The output load resistance can be connected to any power supply voltage within the allowable power supply voltage range and is not limited by the voltage value of the Vcc terminal.
LM393 is a dual voltage comparator integrated circuit. The output load resistance can be connected to any power supply voltage within the allowable power supply voltage range and is not limited by the voltage value of the Vcc terminal. This output can be used as a simple SPS open circuit to ground (when the load resistance is not used), the current sink of the output part is limited by the possible drive and the β value of the device. When the limit current (16mA) is reached, the output transistor will exit and the output voltage will rise quickly.click the link to check
