ULN2003A Review
Worked for 2 mins 57 sec
Reviewed ULN2003AIDR against the TI datasheet. The existing Datasheet URL is already set, so I did not overwrite it; the official TI datasheet I found is
Key specs confirmed
https://www.ti.com/lit/ds/symlink/uln2003ai.pdf.- MPN: ULN2003AIDR
- Manufacturer: Texas Instruments
- Function: 7-channel high-voltage/high-current NPN Darlington transistor array
- Package: SOIC-16, TI package code D / R-PDSO-G16
- Collector-emitter voltage: 50 V max
- Single-channel collector current: 500 mA rated
- Input resistors: 2.7 kΩ series base resistors for TTL / 5 V CMOS drive
- Clamp diodes: Integrated, common cathode at COM
- Temperature range for ULN2003AI: -40 °C to 105 °C
- Thermal, SOIC D: RθJA ≈ 88.6 °C/W
- Pinout: Matches the datasheet.
- Pins 1–7:
1B–7B - Pin 8:
E - Pin 9:
COM - Pins 10–16:
7C–1C
- Pins 1–7:
- Footprint: Matches the SOIC-16 D package geometry: 16 pads, 1.27 mm pitch, ~3.9 mm × 9.9 mm body, compatible with TI’s D package mechanical data.
- Description / MPN / manufacturer / pin count: All consistent.
- All symbol terminals have Pin Type = Unspecified.
1B–7Bshould be inputs.1C–7Cshould be open-collector / low-side outputs.Eshould be documented as common emitter / normally ground.COMshould be documented as clamp-diode common cathode, not a normal supply pin.
- Pin descriptions are missing, so the symbol does not capture important datasheet behavior for
COM,E, and the open-collector outputs. - The stored datasheet is an uploaded PDF copy rather than the canonical TI URL, though it appears to contain the correct TI datasheet content.
Suggested next step: update the pin types and pin descriptions to make the part safer and clearer for schematic/ERC use.
