description/ordering information
The ULN2001A, ULN2002A, ULN2003A,
ULN2004A, ULQ2003A, and ULQ2004A are
high-voltage, high-current Darlington transistor
arrays. Each consists of seven npn Darlington
pairs that feature high-voltage outputs
with common-cathode clamp diodes for switching inductive loads. The collector-current rating of a single
Darlington pair is 500 mA. The Darlington pairs can be paralleled for higher current capability. Applications
include relay drivers, hammer drivers, lamp drivers, display drivers (LED and gas discharge), line drivers, and
logic buffers. For 100-V (otherwise interchangeable) versions of the ULN2003A and ULN2004A, see the
SN75468 and SN75469, respectively.
