Overview
The ULN2003ANE4 is a high-voltage, high-current Darlington transistor array manufactured by Texas Instruments. It contains seven NPN Darlington pairs with common emitters and integrated suppression diodes for inductive load switching. Each channel supports a maximum continuous collector current of 500 mA and withstands up to 50 V collector-emitter voltage. The device features a 2.7 kΩ series base resistor per pair, enabling direct interface with TTL or 5V CMOS logic. It is housed in a 16-pin PDIP package (19.30 mm x 6.35 mm) and operates within a temperature range of -40°C to 70°C.
Feature Summary
- Integrates seven independent NPN Darlington pairs with common cathode clamp diodes for efficient inductive load management.
- Includes internal 2.7 kΩ base resistors to facilitate direct connection to standard TTL and 5V CMOS logic families without external components.
- Supports paralleling of outputs to achieve higher current capabilities beyond the single-channel rating.
Applications
- Relay Drivers
- Stepper and DC Brushed Motor Drivers
- Lamp Drivers
- Display Drivers (LED and Gas Discharge)
- Line Drivers
Procurement Notes
Verify the component authenticity against the official Texas Instruments datasheet specifications. Confirm that the ordering suffix 'E4' corresponds to the specific lead-free material composition defined by the manufacturer. Ensure the physical package dimensions match the 16-pin PDIP format before integration into the design.
Selection Notes
Select this component when driving inductive loads such as relays or solenoids directly from microcontrollers. The 500 mA per channel rating suits moderate power applications. Consider parallel configurations if the load current exceeds individual channel limits. Verify thermal dissipation requirements based on the number of active channels and ambient temperature conditions.
Part Context
This part belongs to the ULx200xA family of high-voltage Darlington arrays. It shares functional similarities with ULN2002A and ULN2004A but differs in input resistor values to optimize compatibility with specific logic voltage levels. The ULN2003ANE4 variant specifically denotes the lead-free PDIP package version within the broader ULN2003A product line.

FAQ
How does the ULN2003ANE4 handle inductive kickback?
The device includes integrated suppression diodes connected between each output and the COM pin. These diodes suppress the reverse voltage generated by inductive loads when the transistors turn off.
Can multiple outputs be used together?
Yes, the Darlington pairs can be paralleled to increase the total current handling capability beyond the single-channel 500 mA limit.
What logic families are compatible with this device?
Due to the 2.7 kΩ series base resistors, the ULN2003ANE4 is compatible with TTL and 5V CMOS logic families.
