| Parameter | LM293DR | LM293DR | Engineering note |
|---|---|---|---|
| Package and exact order code | TI LM293DR: SOIC D package, 8 pins, 2500-unit large tape and reel | UMW LM293DR: SOP-8, 2500-unit tape and reel | Both exact order codes use the standard 8-pin dual-comparator pinout and a 1.27 mm nominal lead pitch. Package naming and final land-pattern release still require independent board checks. |
| Operating temperature range | -25 C to +85 C for the TI LM293DR order code | The reviewed UMW LM293/LM393 datasheet states 0 C to +70 C | The UMW document does not establish operation from -25 C to below 0 C for this target, even though the order code uses the LM293 name. Designs requiring the TI order code's full -25 C to +85 C interval are not covered. |
| Input offset voltage | 5 mV maximum at 25 C; 9 mV maximum over -25 C to +85 C | 5 mV maximum at 25 C; 9 mV maximum over the documented 0 C to +70 C range | The numerical limits correspond, but the target's documented full-range interval is narrower. |
| Supply and response | 2 V to 30 V recommended for non-V devices; 1.3 us typical response | 2 V to 36 V recommended; 1.3 us typical response with 5 mV overdrive | The target document lists a wider supply range and the same typical response. Absolute maximum voltage remains +36 V on both documents. |
| ESD and thermal data | TI specifies 2000 V HBM, 1000 V CDM and SOIC thermal metrics including 148.5 C/W Rtheta-JA | UMW specifies 2000 V HBM and 200 V machine model, but not CDM or an equivalent SOIC thermal-resistance set | Do not copy TI's CDM rating or package thermal resistance to the target. The target separately states 570 mW at 25 C and 5.7 mW/C derating. |
FAE documentary review accepted for the exact TI LM293DR and UMW LM293DR order codes. Both are standard 8-pin dual comparators with 5 mV maximum room-temperature input offset, 9 mV documented full-range maximum, 1.3 us typical response and 2500-unit tape and reel. The reviewed UMW document states only 0 C to +70 C operation even though its exact order code is LM293DR, so this target does not cover the TI order code's -25 C to +85 C interval; applications below 0 C or above +70 C are outside the reviewed target limits. Package naming, land pattern, ESD and thermal margin require independent checks. Document review only; not bench, temperature-cycle, EMC, reliability or production qualified.
