Instructions for Use:
- Supply Voltage: The LM339DT can operate over a wide range of supply voltages, from 2.0V to 36V. Ensure that the supply voltage is within this range to avoid damage to the device.
- Quiescent Current: Each comparator in the LM339DT draws a very low quiescent current, typically around 0.8μA at 5V. This makes it suitable for battery-powered applications.
- Input Offset Voltage: The input offset voltage is typically 2mV at room temperature. This should be considered when designing precision circuits.
- Input Bias Current: The input bias current is very low, typically around 25nA. This helps in minimizing the effect of source impedance on the input signal.
- Input Voltage Range: The inputs can be driven from 0V to VCC - 1.5V. Ensure that the input signals do not exceed these limits to prevent damage or incorrect operation.
- Output Low Voltage: When the output is low, the voltage is typically around 0.1V at a load current of 16mA. This ensures a strong low-level signal.
- Output High Voltage: When the output is high, the voltage is typically around 3.5V at a load current of -0.4mA. This ensures a strong high-level signal.
- Output Sink Current: The output can sink up to 24mA while maintaining a low output voltage. This is useful for driving LEDs or other low-current loads.
- Output Source Current: The output can source up to -0.1mA while maintaining a high output voltage. This is limited compared to the sink capability.
- Propagation Delay Time: The propagation delay time is typically 0.3μs at 5V, which is important for timing-sensitive applications.
- Operating Temperature Range: The device is rated to operate from -40°C to 85°C. Ensure that the ambient temperature does not exceed these limits to maintain reliable operation.

Notes:
- Power Supply Decoupling: Use a 0.1μF ceramic capacitor between VCC and GND close to the IC to reduce noise and improve stability.
- Pull-Up Resistors: The outputs of the LM339DT are open-collector, so pull-up resistors are required to pull the output high. A typical value is 2kΩ to 10kΩ.
- Comparator Operation: The output of each comparator will be low (pulled to ground) if the inverting input (IN-) is more positive than the non-inverting input (IN+). Otherwise, the output will be high (pulled to VCC through the pull-up resistor).
