Frequently Asked Questions
What is the maximum output voltage and current of the ULN2004ADRE4?
The ULN2004ADRE4 supports a maximum output voltage of 50V and a continuous output current of 500mA per channel. All 7 channels can operate simultaneously, making it suitable for driving multiple relays or inductive loads in parallel.
What types of loads can the ULN2004ADRE4 drive?
The ULN2004ADRE4 is designed to drive high-current loads such as relays, solenoids, stepper motors, LED arrays, and incandescent lamps. Its built-in transient suppression diodes provide protection when switching inductive loads like relays and motors.
Is the ULN2004ADRE4 compatible with 3.3V microcontroller logic?
The ULN2004ADRE4 inputs are compatible with CMOS, TTL, and PMOS logic levels. Standard input threshold is approximately 2.7V, so it is generally compatible with 3.3V logic systems, though verifying input voltage levels against the datasheet is recommended for margin-critical designs.
What package does the ULN2004ADRE4 come in?
The ULN2004ADRE4 is available in a 16-pin Small Outline IC (SOIC) package, also designated as R-PDSO-G16. This surface-mount package is well-suited for compact PCB designs and automated assembly processes.
What is the difference between ULN2004A and ULN2003A?
The ULN2004A is optimized for PMOS and CMOS inputs with a higher input threshold of around 2.7V, while the ULN2003A targets TTL and CMOS with a lower threshold of about 1.3V. Both are 7-channel Darlington arrays rated at 50V/500mA, but input compatibility differs based on your logic supply voltage.
