Toshiba ULN2803 DIP


20.00 Rs.

Toshiba ULN2803 DIP8 IC is an Darlington Transistors Arrays Series are high−voltage, high−current Darlington drivers comprised of eight NPN Darlington pairs. Furthermore all units feature integral clamp diodes for switching inductive loads.

  • An integrated circuit is a compact arrangement of transistors and other electronic components that perform specific functions. Also in the case of the ULN2803, it’s a single chip that contains multiple Darlington transistor arrays.
  • 8 Darlington Transistor Arrays are designed to provide 8 separate Darlington transistor arrays. Each of these arrays contains two transistors connected in a particular way to amplify current.

    In this revised version, we’ve eliminated the passive construction and made the sentence more direct and active.

Darlington Transistor:

A Darlington transistor configuration is a type of transistor amplifier circuit that provides high current gain.

Additionally this arrangement results in a high current amplification factor, particularly making it suitable for driving high power loads such as relays, motors, and particularly solenoids.

Engineers commonly use the ULN2803 IC in applications where they must control multiple high-current devices using a microcontroller or another low-power control signal source

Typically, the ULN2803 is used in scenarios where you want to interface low-power digital or microcontroller outputs besides higher-power devices, consequently such as driving multiple relays or stepper motors in various industrial and electronic projects.

Also it simplifies the task of driving these loads by providing a convenient and compact solution with multiple transistor arrays in a single package.
