Frequently Asked Questions
What is the maximum output current and voltage of the ULN2004AID?
The ULN2004AID supports a maximum continuous output sink current of 500mA per channel and a maximum output voltage of 50V. Peak output current can reach 600mA. These ratings make it suitable for driving relays, solenoids, and stepper motor windings directly from logic-level control signals.
What input logic levels are compatible with the ULN2004AID?
The ULN2004AID features standard input characteristics compatible with CMOS, PMOS, NMOS, and TTL logic families. Input threshold voltages are designed to accept standard 5V logic signals, and the input resistors are internally integrated, so no external current-limiting resistors are required when driving from typical microcontroller GPIO pins.
Does the ULN2004AID include flyback diode protection for inductive loads?
Yes, the ULN2004AID includes built-in transient suppression (flyback) diodes on all seven output channels. These clamp voltage spikes generated by inductive loads such as relay coils and solenoids, eliminating the need for external protection diodes and simplifying circuit design.
What package does the ULN2004AID use and what are its dimensions?
The ULN2004AID comes in a 16-pin Small Outline Integrated Circuit (SOIC-16) package, also known as PDSO-G16 per JESD-30. This surface-mount package has a body width of 3.9mm and 1.27mm pin pitch, suitable for automated PCB assembly and high-density board layouts.
What are common alternatives to the ULN2004AID?
Common alternatives include the ULN2003A (7-channel, 500mA, DIP-16 or SOIC-16, TTL/CMOS input), ULN2803A (8-channel Darlington array, 500mA, SOIC-18), and TD62083 from Toshiba. The ULN2004AID is specifically optimized for CMOS/PMOS input compatibility, distinguishing it from ULN2003A which targets TTL inputs.
