LM339ADR Pinout (SOIC-14)

Notes

• LM339ADR is a quad comparator in SOIC-14 package
• All output pins (1OUT, 2OUT, OUT3, OUT4) are open-drain outputs
• VCC (pin 3) and GND (pin 12) are the dual supply pins
• Pin numbering follows standard SOIC-14 convention (counterclockwise from top-left)

at specified free-air temperature, VCC = 5 V (unless otherwise noted)

over operating free-air temperature range (unless otherwise noted) (1)

over operating free-air temperature range (unless otherwise noted)

Typically, the LMx39 compares either a single signal to a reference or two signals. Many users take advantage of the open-drain output to drive the comparison logic output to a logic voltage level to an MCU or logic device. The wide supply range and high voltage capability makes LMx39 optimal for level shifting to a higher or lower voltage.
