The ULN2001A, ULN2002A, ULN2003A, and ULN2004A are 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 inductive loads. The collector-current rating of a single Darlington
pair is 500 mA. The Darlington pairs may 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, see the SN75465 through SN75469.

The ULN2001A is a general-purpose array and can be used with TTL and CMOS technologies. The ULN2002A
is specifically designed for use with 14- to 25-V PMOS devices. Each input of this device has a zener diode and
resistor in series to control the input current to a safe limit. The ULN2003A has a 2.7-k

Ω

 series base resistor

for each Darlington pair for operation directly with TTL or 5-V CMOS devices. The ULN2004A has a 10.5-k

Ω

series base resistor to allow its operation directly from CMOS devices that use supply voltages of 6 to 15 V. The
required input current of the ULN2004A is below that of the ULN2003A, and the required voltage is less than
that required by the ULN2002A.
