Toshiba ULN2803 DIP

Toshiba ULN2803 DIP 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.

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.

Features of Toshiba ULN2803 DIP:

• Output current (single output) 500 mA (max)
• High sustaining voltage output 50 V (min)
• Output clamp diodes
• Inputs compatible with various types of logic.
•  Package Type−APG : DIP−18pin

Specifications

Applications

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.
