The product does not contain any of the restricted substances in concentrations and applications banned by the Directive, and for components, the product is capable of being worked on uln2003ann the higher temperatures required by lead—free soldering.
Typical usage of the ULNA is in driver circuits for relayslamp and LED displaysstepper motors, logic buffers and line drivers.
ULNA – Wikipedia
The seven Darlington pairs in ULN can operate independently except the common cathode diodes that connect to their respective collectors. Generally it can also be used for interfacing with a stepper motorwhere the motor requires high ratings which cannot be provided by other interfacing devices.

A Darlington transistor also known as Darlington pair achieves very high current amplification by connecting two bipolar transistors in direct DC coupling so the current amplified by the first transistor is amplified ulj2003an by the second one.
