LM393 Data

LM393 These devices consist of two independent voltage

comparators that are designed to operate from a

single power supply over a wide range of voltages.

Operation from dual supplies also is possible as

long as the difference between the two supplies is

2 V to 36 V, and VCC is at least 1.5 V more positive than the input common-mode voltage. Current drain is

independent of the supply voltage. The outputs can be connected to other open-collector outputs to achieve

wired-AND relationships.

The LM193 is characterized for operation from −55°C to 125°C. The LM293 and LM293A are characterized for

operation from −25°C to 85°C. The LM393 and LM393A are characterized for operation from 0°C to 70°C. The

LM2903 is characterized for operation from −40°C to 125°C.

Find an analog voltage pulse stretching circuit
I am working on an infrared light transmitting and receiving project. The receiving tube will output a 2uS wide pulse with the same frequency as the input light and variable amplitude according to the
Negative pressure MOS tube switch circuit
How to use transistors and MOS tubes to control the switch of negative voltage, for example, -10V input, I want to use a microcontroller to control the -10V output, how to achieve it, is there any rec
Problems with CPLD driving MAX7219 to transmit 8-bit parameters
I successfully used CPLD to drive MAX7219 to transmit 16-bit parameters. I see that microcontrollers transmit 8 bits of data at a time, and I also want to use CPLD to transmit 8 bits of data. But ther
Automotive electronics such as car chargers and wireless chargers
I'm working on car charger (27W) and wireless charger (maximum 15W) recently, but I can't pass EMC (radiation and conduction). What bothers me most is that I don't have a good design circuit for the f
220V AC to 18V DC
Using a 220V to 18V transformer, the voltage output of the transformer output (pins 12, 14, 17, 19) is 12V. After passing through the MB6S rectifier, the output voltage of pin 3 of SP1 is 27V, and the
