LM293DT

The LM293DT is a dual voltage comparator from STMicroelectronics in an SO-8 package, listed as Active in ST's quality documentation and defined by datasheet DocID2164 Rev 15, whose ordering table carries this exact code. Two independent comparator channels in one small package cover the threshold detection, level monitoring and window-comparison duties that appear throughout power supplies, motor controls and industrial sensing front ends, so one qualified part can serve many board positions and simplify spares holding. Selection advice: verify the exact LM293DT code against your BOM; the not-recommended-for-new-design footnote on the same datasheet applies to the LM193ADT variant only and does not extend to this code, which remains the orderable Active option in SO-8. Parameters verified against STMicroelectronics documentation.
