FAQ

Q: What pull-up resistor value should I use with LM393DT?
A: For 3.3V logic, a 4.7kΩ–10kΩ pull-up to 3.3V is typical. The value balances speed (lower R = faster rise time) against power consumption (higher R = lower current). For 5V logic, 2.2kΩ–10kΩ works well.

Q: How does LM393DT differ from LM339DT?
A: The LM393DT is a dual comparator (2 channels, SO-8), while the LM339DT is a quad comparator (4 channels, SO-14). Both share identical electrical characteristics — choose based on channel count needs.
