ULN2803A datasheet


The ULN2801A, ULN2802A, ULN2803A and ULN2804A each contain eight Darlington transistors with common emitters and integral suppression diodes for inductive loads. Each Darlington features a peak load current rating of 600 mA (500 mA continuous) and can withstand at least 50 V in the OFF state. Outputs may be paralleled for higher current capability.


1. Eight Darlington transistors with common emitters
2. Output current to 500 mA
3. Output voltage to 50 V
4. Integral suppression diodes
5. Versions for all popular logic families
6. Output can be paralleled
7. Inputs pinned opposite outputs to simplify board layout
