description/ordering information
The ULN2003AI is a high-voltage, high-current
Darlington transistor array. This device 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.
The ULN2003AI has a 2.7-kΩ series base resistor for each Darlington pair for operation directly with TTL or 5-V
CMOS devices.

†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 af fect 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), θJA, and TA. The maximum allowable power dissipation at any allowable
ambient temperature is PD = (TJ(max) – TA)/θJA. 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.
