Component

dual comparatoropen collector2 V to 36 Vground-sensing input8-pin

U393 is a dual voltage comparator for single-supply or split-supply threshold detection. Its inputs support ground-referenced signals and its open-collector outputs need external pull-up resistors.

Best for

  • Ground-referenced voltage threshold detection
  • Low-cost dual comparator circuits
  • Logic interface circuits using external pull-ups

Avoid if

  • Rail-to-rail input operation is required
  • A push-pull output is required
  • Operation outside 0 °C to 70 °C is required

Check before use

  • Confirm whether DIP-8 or SOP-8 is supplied
  • Provide an external pull-up resistor for each used output
  • Keep input common-mode voltage below VCC - 1.5 V at 25 °C
