Package and exact order codeTI LM239DR: SOIC D package, 14 pins, 2500-unit large tape and reelUMW LM239DR: SOP-14, 2500-unit tape and reelBoth exact order codes use the standard 14-pin quad-comparator pinout and a 1.27 mm nominal lead pitch. Package naming and land-pattern release still require independent board checks.
Operating temperature range-25 C to +85 C-20 C to +85 CThe target is 5 C narrower at the low-temperature end. A board specified below -20 C is outside the target document's stated range.
Input offset voltage5 mV maximum at 25 C; 9 mV maximum over -25 C to +85 C5 mV maximum at 25 C; 9 mV maximum over -20 C to +85 CThe numerical offset limits match, but the target full-range interval is narrower because of its higher low-temperature limit.
Response time and electrical limits1.3 us typical response with 5 mV overdrive; 2 V to 30 V recommended supply for the non-V device1.3 us typical response with 5 mV overdrive; electrical table characterized with VCC up to 30 VThe documented typical response and tested supply ceiling correspond. Transient, ESD and thermal behavior were not established by this documentation review.

FAE documentary review accepted for the exact TI LM239DR and UMW LM239DR order codes. Both are 14-pin quad comparators with the standard pinout, 5 mV room-temperature input-offset maximum and 1.3 us typical response. The target changes the low-temperature endpoint from -25 C to -20 C; applications below -20 C are not covered by the reviewed target limits. Document review only; not bench, temperature-cycle, EMC, reliability or production qualified.
