LM393DR Overview

The LM393DR is a dual differential voltage comparator from Texas Instruments in a SOIC-8 package on tape and reel. Both comparators run from a single 2 V to 30 V supply, the common-mode input range includes ground, and the open-collector outputs interface directly with TTL, MOS and CMOS logic.

Key Features

  • Two independent comparators in SOIC-8
  • Single supply 2 V to 30 V
  • Common-mode input range includes ground
  • Differential input range equal to the supply voltage
  • Low output saturation voltage
  • Outputs compatible with TTL, MOS and CMOS

Applications

  • Server and power supplies
  • Single-phase UPS
  • Motor drives
  • Building and factory automation
  • Appliances and power tools
