LM339DTR

The LM339 consists of four independent precision voltage comparators integrated into a single package. It is designed to operate from a wide range of power supply voltages, making it versatile for various applications.

Key Features

1. Quad Voltage Comparators: The LM339 contains four comparators, allowing for multiple comparison operations within a single IC.
2. Wide Power Supply Range: It can operate from a single supply voltage ranging from +2V to +36V, or from dual supplies ±1V to ±18V.
3. Low Power Consumption: The power supply current drain is very low and independent of the supply voltage, making it suitable for low-power applications.
4. Low Input Bias and Offset Currents: The input bias current and offset current are low, ensuring accurate comparisons even with small input signals.
5. TTL, DTL, ECL, MOS, and CMOS Compatible: The output of the LM339 is compatible with various logic systems, making it easy to interface with other ICs.
6. High Temperature Range: It can operate within a temperature range of -40°C to +125°C, making it suitable for a wide range of environmental conditions.

Applications

Due to its versatile features, the LM339 is used in various applications such as:

• A/D converters
• Wide range VCO (Voltage-Controlled Oscillator)
• MOS clock generators
• High-voltage logic gates
• Multivibrators

Package and Pin Configuration

The LM339 is typically available in a 14-pin SOP (Small Outline Package) or DIP (Dual In-Line Package) configuration. The pin configuration includes inputs for the four comparators, power supply pins, and output pins for each comparator.

Electrical Characteristics

At specified conditions (e.g., VCC = 5V), the LM339 exhibits certain electrical characteristics such as:

• Input offset voltage: Typically low, with a maximum value specified for each comparator.
• Input bias current: A small current that flows into or out of the input terminals.
• Output saturation voltage: The voltage at the output when it is fully saturated (either high or low).

Additional Notes

• The LM339 is a mature and widely used IC, known for its reliability and performance.
• It should be noted that specific electrical characteristics and performance may vary slightly between different manufacturers and production batches.

In summary, the LM339DTR (or LM339) is a versatile quad voltage comparator IC suitable for a wide range of applications. Its features include a wide power supply range, low power consumption, and compatibility with various logic systems.
