About this product
The LM393 is a dual differential voltage comparator IC that compares two input voltages and outputs a digital high or low signal. It is used for level detection, threshold switching, sensor interfaces and simple oscillators. Its outputs are open-collector, so a pull-up resistor is required.

Frequently asked questions
What is the price of LM393 Dual Differential Voltage Comparator IC in Egypt?
LM393 Dual Differential Voltage Comparator IC currently costs 8 EGP in Egypt.
Where can I buy LM393 Dual Differential Voltage Comparator IC in Egypt?
LM393 Dual Differential Voltage Comparator IC is available from RAM Electronics. Compare the offers above to find the best price.
Why does the LM393 output not go high?
Its outputs are open-collector, so they can only pull low. Add a pull-up resistor (commonly 10 kΩ) from the output to the supply voltage to get a high level.
Can I run the LM393 from a 5 V supply with an Arduino?
Yes. The LM393 works from a single supply in the 2 V to 36 V range, so 5 V is fine. Connect the output to the Arduino input through a pull-up to 5 V, and make sure the unused comparator's inputs are defined.
