Overview
The ULN2003F12FN-7 is a multi-channel sink driver manufactured by Diodes Incorporated, featuring four output stages in a DFN3030-10 package. It supports 3.3V to 5V CMOS logic inputs and provides low output voltage levels of 0.6V typical at 140mA sink current under 5.0V logic input conditions. The device includes internal free-wheeling diodes connected to the COM pin for inductive kick-back protection and incorporates an input RC snubber circuit to eliminate spurious operation in noisy environments. An internal pull-down resistor allows tri-stating the input driver.
Feature Summary
- Four-channel high-current sink drivers with integrated free-wheeling diodes for inductive load protection
- Compatible with 3.3V and 5.0V micro-controller logic interfaces
- Input RC-snubber circuit designed to eliminate spurious operation in noisy environments
- Internal pull-down resistors allow tri-stating the input driver
Applications
- Relay driver applications
- Stepping motor applications
- Logic level shifter
Procurement Notes
Verify component authenticity through authorized Diodes Incorporated distributors or direct manufacturer channels. Confirm compliance with RoHS 3 and lead-free specifications. Ensure proper handling procedures are followed due to ESD sensitivity ratings of 4kV HBM and 1kV CDM. Validate packaging integrity for tape and reel delivery containing 3,000 units per reel.
Selection Notes
Select this part when four independent sink channels are required in a compact surface-mount footprint. The DFN3030-10 package offers thermal resistance of 65°C/W junction-to-ambient. Consider parallel channel usage if higher combined current capability up to 1.0A is needed. Verify compatibility with 3.3V or 5.0V logic families before implementation.
Part Context
This component belongs to the ULN2003V12 and ULN2003F12 family of multi-channel relay and inductive load sink drivers. It serves as a lower-power variant compared to traditional ULN2003A devices, offering reduced on-chip power dissipation while maintaining compatibility with standard logic interfaces. The F12 designation indicates the four-channel configuration within this product line.
Replacement Considerations
Public confirmed substitute part numbers: ULN2003ADR (Texas Instruments), MC1413DR2G (onsemi). Verify pinout compatibility and electrical characteristics match before substitution.
FAQ
What is the maximum continuous sink current per channel?
The maximum continuous sink current per channel is 140mA at 5.0V logic input and 100mA at 3.3V logic input.
How does the device handle inductive loads?
Each output features an internal free-wheeling diode connected in a common-cathode configuration at the COM pin, providing flexibility for increasing current sink capability and protecting against inductive kick-back.
Can the input be tri-stated?
Yes, the internal pull-down resistor at the input stage helps allow the input logic to be tri-stated.
