Product details

What this driver is and where it fits

The Texas Instruments ULQ2004ADR is a 7-channel NPN Darlington transistor array configured as a low-side switch, designed to drive relays, solenoids, stepper motors, and other inductive or resistive loads from logic-level control signals. Each of the seven outputs is rated for 500 mA continuous current and can handle a load voltage up to 50 V.

Package and rework — 16-SOIC is bench-friendly

The ULQ2004ADR comes in a 16-SOIC body measuring 3.90 mm wide — a standard footprint that reflows cleanly with a hot-air station or convection oven.

Lifecycle and sourcing reality

It remains a standard catalog item from Texas Instruments, part of the ULx200xA series that has been in continuous production for decades. This part is RoHS3 compliant.

Frequently asked questions

What is the maximum output current of ULQ2004ADR?

This is the per-channel limit; the total package current is thermally derated when all channels are active simultaneously.

What is the closest pin-compatible alternative to ULQ2004ADR in this component family?

The ULN2004A is the same Darlington array in DIP-16 or SOIC-16 packages, with identical pinout and electrical ratings. The ULQ2004A is the automotive AEC-Q100 qualified variant. Both are direct functional replacements for the ULQ2004ADR.

Is ULQ2004ADR compatible with 5V logic?

Yes, the inputs are inverting and accept standard TTL or 5 V CMOS logic levels directly. No external base resistors or level shifters are needed when driving from a 5 V microcontroller or FPGA output.
