ULN2004ADR TI Power Distribution Switches

The ULN2004ADR is a high-voltage high-current Darlington transistor array from Texas Instruments in SOIC-16 surface-mount package, featuring seven independent Darlington pairs with common emitters and integral suppression diodes . For selection, verify output voltage rating of 50V, continuous output current up to 500mA per channel, input compatible with 14V-25V logic signals (for ULN2004A), 10.5kΩ series base resistors, peak surge current capability, and operating temperature from -20°C to +70°C . Features include output clamp diodes for inductive load transient protection, collector-emitter saturation voltage of 1.1V typical at 350mA, and multiple package options. Ideal for relay drivers, stepper motor drivers, solenoid and valve controllers, LED and incandescent lamp displays, logic buffers, and any medium-current load driving application requiring 14V-25V logic compatibility with built-in protection .
