LM239DR2G Typical application Circuitry

LM239DR2G

The LM239DR2G is a part of the esteemed LM239 series, a collection of quadruple, differential comparators, designed for applications that necessitate a precise voltage comparison. This integrated circuit is specifically tailored to fulfill roles in level detection and for interfacing with digital logic systems, often utilized in industrial, automotive, and consumer electronics.

1. Voltage Supply Assignments:

- Pin 11 (Vcc+): This is the pin where the positive supply voltage is applied. The LM239DR2G operates over a range of supply voltages from 2 V to 36 V or ±1 V to ±18 V for dual supplies.

- Pin 4 (GND): Connect this pin to the system's ground to establish a common reference for the comparators.

2. Comparator Inputs Layout:

- Pins 5, 6, 8, 9 (Non-Inverting Inputs): These pins are the non-inverting (+) inputs of the LM239DR2G's individual comparators.

- Pins 2, 3, 12, 13 (Inverting Inputs): These pins serve as the inverting (−) inputs for the four comparators in the LM239DR2G.

3. Output Configuration:

- Pins 1, 7, 14, 10 (Outputs): The LM239DR2G expresses its comparative verdicts on these pins. The outputs are open-collector, necessitating an external pull-up resistor to provide a high-level output voltage.

4. External Components for Enhanced Functionality:

- Feedback and Biasing Circuitry: External resistors or diodes can be connected to the LM239DR2G's input pins to implement hysteresis or set thresholds, as the IC does not have internal feedback mechanisms.

5. Digital Logic Compatibility:

- Pull-up Resistors on Outputs: To ensure the LM239DR2G interfaces effectively with digital logic, affixing pull-up resistors to the output pins is required to define the logic high level when the output transistor is off.

When integrating the LM239DR2G into a circuit, designers should meticulously review the datasheet for the absolute maximum ratings to prevent any condition that could lead to device failure. For effective noise suppression, decoupling capacitors are recommended near the supply pins. The layout of the printed circuit board should take into consideration the routing of signals to minimize interference-especially keeping the analog inputs away from noisy digital tracks.

In summary, the LM239DR2G offers a reliable solution for voltage comparison functions, boasting four comparators in a single package, which significantly economizes space and improves performance in complex electronic systems.
