- 7 / 8 Darlington arrays per package
- 500 mA rated collector current — single output
- 50 V output voltage
- Inputs compatible with various types of logic
| Device | Output | Channels | VCE abs. [V] | VIN abs. [V] | IC max. [mA] | Package |
|---|---|---|---|---|---|---|
| ULN2003A | Sink | 7 | 50 | 30 | 500 | SOP-16 DIP-16 |
| ULN2803A | Sink | 8 | 50 | 30 | 500 | SOP-18 DIP-18 |
Both families: VCE(sat) max. 1.3 V at IC = 200 mA. Maximum ratings are limits; check thermal dissipation and duty cycle. 500 mA does not apply simultaneously to all outputs.
Applications
- Relay drivers
- Stepper and brushed DC motor driver circuits
- Logic buffers
Original HTC family illustrations. SOP-16/18 and DIP-16/18 shown as in the catalog; confirm the exact ordering variant and circuit requirements before design-in.
