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.","metaTitle":"ULQ2004ADR 7-Ch NPN Low-Side Driver, 500mA, 50V, SOIC-16","metaDescription":"ULQ2004ADR is a 7-channel NPN low-side driver rated 500mA per output, 50V load max.
