Overview
The ULN2004AINSE4 is a high-voltage, high-current Darlington transistor array manufactured by Texas Instruments. It comprises seven NPN Darlington pairs with common emitters and integrated clamp diodes for switching inductive loads. Each pair supports a collector current of 500 mA, which can be paralleled for higher capacity. The device features a 10.5 kΩ series base resistor per channel, enabling direct interface with CMOS logic operating from 6 V to 15 V supplies. It operates within a temperature range of -40 °C to +105 °C and is housed in a 16-pin SOIC package.
Feature Summary
- Integrated 10.5 kΩ base resistors facilitate direct connection to 6 V–15 V CMOS logic without external components.
- Seven independent NPN Darlington channels provide high-voltage output capability up to 50 V.
- Common cathode clamp diodes are included on each channel to suppress voltage spikes from inductive loads.
Applications
- Relay driver circuits
- Stepper motor and DC brushed motor drivers
- High-voltage line drivers
Procurement Notes
Verify the suffix E4 indicates lead-free compliance when sourcing. Confirm the specific manufacturer source, as this part number may be distributed through authorized channels or secondary markets. Ensure the component matches the required SOIC-16 package dimensions and thermal specifications for the intended application environment.
Selection Notes
Select this component when interfacing 6 V to 15 V CMOS logic with high-voltage inductive loads requiring up to 500 mA per channel. The internal 10.5 kΩ resistors simplify design compared to other variants like the ULN2003A. Consider parallel operation if total load current exceeds single-channel ratings.
Part Context
This component belongs to the ULx200xA family of Darlington arrays. Unlike the ULN2003A which uses 2.7 kΩ resistors for TTL/5V compatibility, the ULN2004A variant utilizes 10.5 kΩ resistors optimized for higher voltage CMOS inputs. The E4 suffix typically denotes environmental compliance regarding lead content.
Replacement Considerations
The ULN2004AN serves as a pin-compatible through-hole alternative. For surface mount applications, verify availability of the standard ULN2004AIN. Cross-reference with ULQ2004A for automotive-grade requirements if applicable.
