Description

The ULN2001A, ULN2002A, ULN2003A,ULN2004A, ULQ2003A, and ULQ2004A arehigh-voltage, high-current Darlington transistorarrays. Each consists of seven npn Darlingtonpairs that feature high-voltage outputswith common-cathode clamp diodes for switching inductive loads. The collector-current rating of a singleDarlington pair is 500 mA. The Darlington pairs can be paralleled for higher current capability. Applicationsinclude relay drivers, hammer drivers, lamp drivers, display drivers (LED and gas discharge), line drivers, andlogic buffers. For 100-V (otherwise interchangeable) versions of the ULN2003A and ULN2004A, see theSN75468 and SN75469, respectively.

The ULN2001A is a general-purpose array and can be used with TTL and CMOS technologies. The ULN2002Ais designed specifically for use with 14-V to 25-V PMOS devices. Each input of this device has a Zener diodeand resistor in series to control the input current to a safe limit. The ULN2003A and ULQ2003A have a 2.7-kseries base resistor for each Darlington pair for operation directly with TTL or 5-V CMOS devices. TheULN2004A and ULQ2004A have a 10.5-kseries base resistor to allow operation directly from CMOS devicesthat use supply voltages of 6 V to 15 V. The required input current of the ULN/ULQ2004A is below that of theULN/ULQ2003A, and the required voltage is less than that required by the ULN2002A.
