ULN2004A
HIGH VOLTAGE, HIGH CURRENT
DARLINGTON TRANSISTOR ARRAYS
Description
The ULN2002A, ULN2003A and ULN2004A are high voltage, high
current Darlington arrays each containing seven open collector
common emitter pairs. Each pair is rated at 500mA. Suppression
diodes are included for inductive load driving, the inputs and outputs
are pinned in opposition to simplify board layout.
Device options are designed to be compatible with common logic
families:
ULN2002A (14-25V PMOS)
ULN2003A (5V TTL, CMOS)
ULN2004A (6-15V CMOS, PMOS)
These devices are capable of driving a wide range of loads including
solenoids, relays, DC motors, LED displays, filament lamps, thermal
print-heads and high-power buffers.
The ULN2002A, ULN2003A and ULN2004A are available in both a
small outline 16-pin package (SO-16) and PDIP-16 package.

Notes: 4. Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only. 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.
5. All voltage values are with respect to the emitter/substrate terminal E, unless otherwise noted.
6. 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.
7. Maximum power dissipation is a function of TJ(max), θJC and TA. The maximum allowable power dissipation at any allowable ambient temperature
is PD = (TJ(max) – TC)/θJC. Operating at the absolute maximum TJ of +150°C can affect reliability.
