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.

description/ordering information (continued)
The ULN2001A is a general-purpose array and can be used with TTL and CMOS technologies. The ULN2002A
is designed specifically for use with 14-V 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 and ULQ2003A have a 2.7-k
series base resistor for each Darlington pair for operation directly with TTL or 5-V CMOS devices. The
ULN2004A and ULQ2004A have a 10.5-k
series base resistor to allow operation directly from CMOS devices
that use supply voltages of 6 V to 15 V. The required input current of the ULN/ULQ2004A is below that of the
ULN/ULQ2003A, and the required voltage is less than that required by the ULN2002A.

Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES:
1. All voltage values are with respect to the emitter/substrate terminal E, unless otherwise noted.
2. Maximum power dissipation is a function of TJ(max),
JA, and TA. The maximum allowable power dissipation at any allowable
ambient temperature is PD = (TJ(max) TA)/
JA. Operating at the absolute maximum TJ of 150
C can affect reliability.
3. The package thermal impedance is calculated in accordance with JESD 51-7.
4. Maximum power dissipation is a function of TJ(max),
JC, and TC. The maximum allowable power dissipation at any allowable case
temperature is PD = (TJ(max) TC)/
JC. Operating at the absolute maximum TJ of 150
C can affect reliability.
5. The package thermal impedance is calculated in accordance with MIL-STD-883.
