| Parameter | LM393ADR | LM393ADR | Engineering note |
|---|---|---|---|
| Package and exact order code | TI LM393ADR: SOIC D package, 8 pins, 2500-unit large tape and reel | UMW LM393ADR: SOP-8, 2500-unit tape and reel | Both exact codes use the standard 8-pin dual-comparator pinout and a nominal 1.27 mm lead pitch. TI calls the package SOIC while UMW calls it SOP; the final land pattern, paste aperture and assembly tolerances require independent release checks. |
| Temperature and input offset voltage | 0 C to +70 C; 2 mV maximum at 25 C and 4 mV maximum over temperature | 0 C to +70 C; approximately 5 mV maximum at 25 C and 9 mV maximum over temperature | The exact ambient range matches, but the target's documented accuracy window is materially wider despite the A in its order code. Precision thresholds, low-level sensing and comparator-window margin require a new error budget; this is not an equivalent A-grade offset guarantee. |
| Response and supply | 1.3 us typical response; recommended supply up to 36 V total or +/-18 V | 1.3 us typical response; electrical characterization documented up to a 36 V supply | The documented typical response and tested supply ceiling correspond. Input common-mode range, output pull-up, load capacitance and the intended overdrive must still be checked at the application limits. |
| ESD and thermal characterization | TI specifies HBM +/-2000 V, CDM +/-1000 V and SOIC RthJA of 148.5 C/W | UMW specifies HBM 2000 V and machine model 200 V; an equivalent CDM and thermal-resistance set was not found | Do not copy TI's CDM, junction-temperature or thermal-resistance limits to the target. Board-level ESD, thermal margin and worst-case load conditions require independent evaluation. |
FAE documentary review accepted for the exact TI LM393ADR and UMW LM393ADR order codes. Both are 8-pin dual comparators with the standard pinout, 0 C to +70 C exact-order rating, 2500-unit tape and reel and 1.3 us typical response. The target's reviewed input-offset limits are approximately 5 mV maximum at 25 C and 9 mV maximum over temperature versus TI's 2 mV and 4 mV, so the matching surname does not establish equivalent precision. UMW provides no equivalent CDM or thermal-resistance set in the reviewed datasheet. Document review only; no bench, temperature-cycle, EMC, reliability or production qualification was performed.
