DARLINGTON TRANSISTOR ARRAY
SLRS054B JULY 2003 REVISED FEBRUARY 2005
500-mA-Rated Collector Current (Single
Output)
High-Voltage Outputs . . . 50 V
Output Clamp Diodes
Inputs Compatible With Various Types of
Logic
Relay-Driver Applications
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.
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 affect device reliability.
(2)
All voltage values are with respect to the emitter/substrate terminal E, unless otherwise noted.

The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in
a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.

Eco Plan - May not be currently available - please check
http://www.ti.com/productcontent
for the latest availability information and additional
product content details.
None: Not yet available Lead (Pb-Free).
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Green (RoHS & no Sb/Br): TI defines "Green" to mean "Pb-Free" and in addition, uses package materials that do not contain halogens,
including bromine (Br) or antimony (Sb) above 0.1% of total product weight.
