description

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