It features uln2004a datasheet flyback diodes for switching inductive loads. 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. The drivers can be paralleled ratasheet even higher current output. The resultant current gain is the product of those of the two component transistors:. Who We Are Management.


Product is in design feasibility stage. The ULN is known for its high-current, high-voltage capacity. Typical usage of the ULNA is in driver circuits for relayslamp and LED displaysstepper motors, logic buffers and line drivers.
