ULN2003A

ULN2003A is a seven-channel Darlington transistor array from UMW in the maker’s SOP-16 body — UMW package code SOP-16-225-1.27, halogen-free, tape and reel — with the bare code verified as the maker’s own order string in the ordering table of UMW’s ULN2003A manual (R3.10); the DIP form in the same book is a separate code (ULN2003AN). Verified figures are UMW’s own, not read across from any other maker: input voltage range of −0.5 V to 30 V, output voltage of 50 V maximum, output current of 500 mA per channel, collector-emitter saturation voltage of 0.9 V typical and 1.1 V maximum at 100 mA and 1.3 V typical and 1.6 V maximum at 350 mA, input-on voltage maxima of 2.4 V, 2.7 V and 3.0 V by channel current, input-on current of 0.93 mA typical and 1.35 mA maximum, clamp-diode reverse voltage of 50 V, output leakage of 20 µA maximum, and an operating range of −40 °C to +85 °C. The selection point is seven relay and lamp drivers with integral clamp diodes in a narrow 16-pin body. Selection advice: two other makers’ ULN2003 rows sit in this catalog — ST’s ULN2003D1013TR in SO-16 and TI’s ULN2003A family — and each page carries its own maker’s datasheet figures; a maker substitution is a documentation change even where the array function matches, so state the maker in the RFQ. Parameters verified against the UMW ULN2003A datasheet.
