About this product
The LM393 contains two independent voltage comparators with open-collector outputs, able to run from a single supply. It compares two voltages and switches its output accordingly, and is used in level detection, threshold alarms, simple oscillators and light-sensor or line-follower circuits.

Frequently asked questions
What is the price of LM393 Dual Differential Voltage Comparator (SMD) in Egypt?
LM393 Dual Differential Voltage Comparator (SMD) currently costs 8 EGP in Egypt.
Where can I buy LM393 Dual Differential Voltage Comparator (SMD) in Egypt?
LM393 Dual Differential Voltage Comparator (SMD) is available from RAM Electronics. Compare the offers above to find the best price.
Why does the output need a pull-up resistor?
The open-collector output can only pull the line low. Connect a pull-up resistor, commonly around 10 kΩ, from the output to the supply or logic rail so that the output can read as high.
Can I run the LM393 from a 3.3 V supply?
Yes. The single-supply range starts at 2 V, so a 3.3 V supply is within the specified range. Make sure the input voltages stay within the common-mode range given in the datasheet.
