ULN2803LW Description

Short technical summary and product information.

The ULN2803LW from Allegro Microsystems is a high-voltage, high-current Darlington array designed for interfacing low-level logic circuitry with peripheral power loads. This component features eight open-collector outputs, each capable of sinking continuous load current up to 500 mA and withstanding up to 50 V in the off state.

 

With inputs compatible with TTL, DTL, PMOS, or CMOS logic levels, the ULN2803LW is versatile for various applications. It includes integral clamp diodes for transient protection on the outputs. The device is supplied in an 18-lead small-outline plastic package (SOIC), suitable for surface mount assembly.

 

Typical applications for the ULN2803LW include driving relays, solenoids, stepping motors, LED displays, and heaters. The series input resistors are selected for direct operation with 5 V TTL or CMOS logic. Outputs can be paralleled for higher load current requirements.
