HIGH-VOLTAGE HIGH-CURRENT
DARLINGTON TRANSISTOR ARRAY
ULN2003A
DESCRIPTION
The ULN2003A is monolithic 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 ind-
uctive loads. The collector-current rating of a single
Darlington pair is 500mA. The Darlington pairs may be
paralleled for higher current capability. Applications in-
clude relay drivers, hammer drivers, lamp drivers, dis-
play drivers (LED and gas discharge), line drivers,
and logic buffers.
The ULN2003A has a 2.7kΩ ҏseries base resistor for
each Darlington pair for operation directly with TTL or
5-V CMOS devices.
