Ideally Suited For Interfacing Between Low-level Logic Circuitry And Multiple Peripheral Power
Loads, The Series Uln20xxa/l High-voltage, High-current Darlington Arrays Feature Continuous Load
Current Ratings To 500 Ma For Each Of The Seven Drivers. At An Appropriate Duty Cycle Depending On
Ambient Temperature And Number Of Drivers Turned On Simultaneously, Typical Power Loads Totaling
Over 230 W (350 Ma X 7, 95 V) Can Be Controlled. Typical Loads Include Relays, Solenoids, Stepping
Motors, Magnetic Print Hammers, Multiplexed Led And Incandescent Displays, And Heaters. All Devices
feature open-collector outputs with integral clamp diodes.
The Uln2003a/l And Uln2023a/l Have Series Input Resistors Selected For Operation Directly With 5 V
Ttl Or Cmos. These Devices Will Handle Numerous Interface Needs - Particularly Those Beyond The
capabilities of standard logic buffers.
The Uln2004a/l And Uln2024a/l Have Series Input Resistors For Operation Directly From 6 To 15 V Cmos
or PMOS logic outputs.
The Uln2003a/l And Uln2004a/l Are The Standard Darlington Arrays. The Outputs Are Capable Of Sinking
500 Ma And Will Withstand At Least 50 V In The Off State. Outputs May Be Paralleled For Higher Load
Current Capability. The Uln2023a/l And Uln2024a/l Will Withstand 95 V In The Off State.
These Darlington Arrays Are Furnished In 16-pin Dual In-line Plastic Packages (suffix "a") And
16-lead Surface-mountable Soics (suffix "l"). All Devices Are Pinned With Outputs Opposite Inputs To
Facilitate Ease Of Circuit Board Layout. All Devices Are Rated For Operation Over The Temperature
Range Of -20 C To +85 C. Most (see Matrix, Next Page) Are Also Available For Operation To -40 C;

Description
The Uln2001a, Uln2002a, Uln2003a, And Uln2004a Are Monolithic 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 May 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, See The
SN75465 through SN75469.
The Uln2001a Is A General-purpose Array And Can Be Used With Ttl And Cmos Technologies. The Uln2002a
Is Specifically Designed For Use With 14- 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 Has A
2.7-k Series Base Resistor For Each Darlington Pair For Operation Directly With Ttl Or 5-v Cmos
Devices. The Uln2004a Has A 10.5-k Series Base Resistor To Allow Its Operation Directly From Cmos
Devices That Use Supply Voltages Of 6 To 15 V. The Required Input Current Of The Uln2004a Is Below
That Of The Uln2003a, And The Required Voltage Is Less Than That Required By The Uln2002a.
