| Market Reality | - | The LM393 is the dual voltage comparator behind every threshold, window and alarm decision in instruments and industrial boards: 2V to 36V supply, ground-sensing inputs, open-collector outputs, and an 8-pin map that is identical to the LM358 op-amp pinout - the twin arrangement that makes socket-level swaps look possible and schematic-level swaps dangerous. Its family tree covers the whole repair shelf: temperature-grade siblings (LM193 / LM293 / LM2903 automotive) and the quad LM339 for four-channel boards. The two failure stories this page exists for: a comparator that stopped switching because the pull-up is missing, and an op-amp fitted into a comparator socket that saturates slowly and cannot wire-OR. |
