The UTC LM339 consists of four independent voltage comparators designed specifically to operate from a single power supply over a wide voltage range. Operation from split power supplies is also possible, and the low power supply current drain is independent of the magnitude of the power supply voltage. These comparators also have a unique characteristic in that the input common-mode voltage range includes ground, even though they are operated from a single power supply voltage.

Features

  • Wide Supply Voltage Range
  • LM139/139A Series 2 to 36 VDC or ±1 to ±18 VDC

  • LM3302-N: 2 to 28 VDC or ±1 to ±14 VDC
  • Very Low Supply Current Drain (0.8 mA) — Independent of Supply Voltage
  • Low Input Biasing Current: 25 nA
  • Low Input Offset Current: ±5 nA
  • Offset Voltage: ±3 mV
  • Input Common-Mode Voltage Range Includes GND
  • Differential Input Voltage Range Equal to the Power Supply Voltage
  • Low Output Saturation Voltage: 250 mV at 4 mA
  • Output Voltage Compatible With TTL, DTL, ECL, MOS, and CMOS Logic Systems
