TEXAS INSTRUMENTS LM339N/NOPB Precision Quad Comparator DIP 14-Pin

The TEXAS INSTRUMENTS LM339N/NOPB is a low-power, low-offset voltage quad comparator designed for precision sensing and control applications. With an offset voltage specification as low as 2 mV maximum across all four comparators, this device delivers accurate and reliable performance in demanding environments.

This comparator operates from a single power supply over a wide voltage range, and can also function with split power supplies. The low supply current drain (0.8 mA) remains independent of the supply voltage magnitude, making it ideal for battery-powered equipment. The input common-mode voltage range includes ground, allowing sensing near GND even with a single supply.

Key Features

• Low power consumption: 0.8 mA supply current
• Input common-mode range includes ground
• Differential input voltage range equals power supply voltage
• Output compatible with TTL, DTL, ECL, MOS, and CMOS logic
• Reduced VOS drift over temperature
• Eliminates need for dual supplies in most applications
• Green product, free from Sb/Br

The device interfaces directly with TTL and CMOS logic, and with MOS logic when operated from dual supplies. It is supplied in a 14-pin DIP package with through-hole mounting for easy integration into PCB designs.
