Overview
The ULN2004ANG4 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 driving. The device features a 16-pin DIP package and supports an output voltage of 50 V with a continuous collector current of 500 mA per driver. It includes a 10.5 kΩ series base resistor, enabling direct interface with CMOS logic families operating between 6 V and 15 V.
Feature Summary
- Integrated suppression diodes facilitate the switching of inductive loads without external components.
- Input pins are positioned opposite to output pins to simplify printed circuit board layout.
- Outputs can be paralleled to achieve higher current capabilities beyond single-channel ratings.
Applications
- Relay drivers
- Stepper and DC brushed motor drivers
- LED and gas discharge tube display drivers
- Line drivers and logic buffers
Procurement Notes
Verify the specific suffix 'G4' indicates lead-free compliance and RoHS status according to the manufacturer's datasheet. Confirm the package type matches the required DIP-16 form factor for the target application. Ensure the input voltage range aligns with the 6 V to 15 V CMOS specification provided in the official documentation.
Selection Notes
Select this component when interfacing with 6 V to 15 V CMOS or PMOS logic families due to its specific 10.5 kΩ base resistor configuration. Choose the ULN2004ANG4 over other variants if through-hole mounting is required. Verify that the 50 V output voltage rating meets the load requirements.
Part Context
This part belongs to the ULx200xA series of high-voltage Darlington arrays from Texas Instruments. It shares the same internal architecture as the ULN2004A but carries the G4 suffix, which typically denotes environmental compliance attributes such as lead-free manufacturing. It is functionally distinct from the ULN2003A, which is optimized for 5 V TTL/CMOS interfaces.
Replacement Considerations
The ULN2004A is the standard equivalent part number. Other manufacturers offer compatible parts such as the STMicroelectronics ULN2004A or the ON Semiconductor MC1413, though pinout and electrical characteristics should be verified against the TI datasheet before substitution.
