UMW · Interface ICs
| Parameter | ULN2003ADR | ULN2003A | Engineering note |
|---|---|---|---|
| Package and order code | SOIC D, 16 pins, 2500 pieces on a large reel | SOP-16, UMW ULN2003A, 2500 pieces on a reel | Both are 16-pin narrow surface-mount Darlington arrays with the same pin functions. Verify the land pattern and reel format before production. |
| Operating ambient temperature | -40 C to +70 C | -40 C to +85 C | The target publishes a wider ambient operating range. |
| Output leakage current at 50 V | 50 uA maximum at +25 C; 100 uA maximum at +70 C | 20 uA maximum at +25 C; 100 uA maximum at +85 C | The target has a tighter room-temperature maximum and specifies its high-temperature limit at +85 C. |
| Thermal resistance | 88.6 C/W junction-to-ambient for the SOIC D package | No junction-to-ambient thermal resistance or derating table found in the reviewed document | Thermal headroom for multi-channel loads must be established separately from the source datasheet. |
| ESD ratings | 2000 V HBM and 500 V CDM | No ESD rating found in the reviewed document | The reviewed UMW document does not support an ESD-equivalence claim. |
FAE documentary review accepted for the exact TI ULN2003ADR and UMW ULN2003A order codes. Both are seven-channel, 50 V, 500 mA Darlington arrays with clamp diodes and the same 1B-7B, E, COM and 1C-7C pin functions. The reviewed electrical limits match for input current, saturation voltage and clamp forward voltage. The target lacks published thermal-resistance and ESD ratings, and package/land-pattern details must be checked. Document review only; not bench, reliability or production qualified.
