Overview
The ULN2003V12PWR is a high-voltage, high-current Darlington transistor array manufactured by Texas Instruments. It integrates seven independent Darlington pairs with common emitters and open-collector outputs within a single TSSOP-16 package. Designed for low-side switching applications, it operates on a power supply voltage range of 3.3 V to 5 V. Each channel provides an output current capability of up to 140 mA. The device includes integrated suppression diodes for inductive loads and features TTL/CMOS compatibility. It functions reliably across an extended temperature range from -40°C to +125°C.
Feature Summary
- Integrates seven high-voltage Darlington pairs with common emitters for multi-channel control
- Includes built-in clamping diodes to protect against inductive load back-EMF
- Features input pins positioned opposite output pins to facilitate PCB layout
Applications
- Relay drivers
- Stepper motor drivers
- DC brushed motor drivers
- LED and gas discharge lamp drivers
- Logic buffer circuits
Procurement Notes
Verify the specific suffix 'V12' against the official Texas Instruments datasheet to confirm pinout and electrical characteristics match the standard ULN2003 family. Ensure the TSSOP-16 tape-and-reel packaging aligns with automated assembly requirements. Cross-reference the manufacturer date code and lot traceability to ensure component authenticity and compliance with project specifications.
Selection Notes
Select this component when driving multiple low-voltage loads requiring up to 140 mA per channel. The TSSOP-16 surface-mount package is suitable for space-constrained designs. Verify that the 3.3 V to 5 V operating range matches the system logic levels. Consider thermal dissipation capabilities if multiple channels are driven simultaneously at maximum current limits.
Part Context
This part belongs to the ULN2003 series of Darlington arrays, widely used for interfacing microcontrollers with higher power devices. The 'V12' suffix typically denotes a specific manufacturing variant or revision within the Texas Instruments portfolio. It serves as a direct replacement for discrete transistor networks, simplifying circuit design for relay and motor control applications.
Replacement Considerations
The ULN2003AN (PDIP) offers identical functionality but in a through-hole package. For surface-mount alternatives, check for other ULN2003 variants in SOIC or TSSOP packages from Texas Instruments or authorized equivalents. Ensure any substitute maintains the 7-channel configuration and compatible input/output pinouts.
