Application Scenarios & Design Considerations

LOW POWER SINGLE VOLTAGE COMPARATOR

Alternative Part Number

  • LM393DR --: Industry-standard dual comparator with similar open-collector output and wide supply range, pin-compatible in most SOIC-8 designs and widely available.
  • LM2903DR --: Dual differential comparator rated for extended temperature range, functionally equivalent to the TS391 and a common drop-in replacement in SOIC-8 packages.
  • BA10393F-E2 --: Dual comparator from a different series with open-collector output and comparable supply voltage range, suitable as a cross-manufacturer alternative.
