The following two tabs change content below. Uln2008 datasheet quote online easily: Views Read Edit View history. Input for 3 rd channel. A darlington pair is an arrangement of two datashheet transistors.

Working of ULN IC – Gadgetronicx

Frank Donald is an Electronics and Communication Engineer who loves building stuff in his free time. Frank Donald September 16, 0 Dataheet. In this pair the current amplified by the first transistor is further amplified by the next transistor providing high current to the output terminal.

The resultant current gain is uln2008 datasheet product of those of the uln2008 datasheet component transistors:.

Output for 2 nd channel. SPI Module of Arduino. A Darlignton pair is two transistors that act as a single transistor providing high current gain. Input for 6 th channel.

The seven Darlington pairs in ULN can operate independently except the uln2008 datasheet cathode eatasheet that connect to their respective collectors. Input for uln2008 datasheet nd channel. Output for uln2008 datasheet th channel. By uln2008 datasheet this site, you agree to the Terms of Use and Privacy Policy.

Video games, blogging and programming are the things he loves most. Thic IC consists of a eight NPN Darlington connected transistors with common Clamp diodes for switching the loads connected to the output.

Articles which use infobox templates with no data rows. It features common-cathode flyback diodes for switching inductive loads.

Input for 7 th channel. Common free wheeling diodes. When high logic is fed to uln2008 datasheet input both the transistors begin to conduct providing a path to ground for the external load that the output is connected.

Output uln2008 datasheet 4 th channel. Wikimedia Commons has media related to ULN Even further, stacking one chip on top of another, uln2008 datasheet electrically and physically, has been done. Different versions of this family interface to different logic families.

Notify of all uln208 follow-up comments Notify of new replies to all my comments.

Output for 7 th channel. Interface SD Card with Arduino. In other projects Wikimedia Commons. Skip to main content. A Darlington transistor also known as Darlington uln2008 datasheet achieves very high current amplification by connecting two bipolar transistors in uln2008 datasheet DC coupling so the current amplified by the first transistor is amplified further by the second one.

ULN is also commonly used while driving Stepper Motors. Output for 1 st channel. The ULN is known for its high-current, high-voltage capacity. Input for 1 st channel. From Wikipedia, the free encyclopedia. Thus when an input is applied corresponding output pin drops down to zero there by enabling uln2008 datasheet load connected to complete uln2008 datasheet path.

The inputs and outputs are provided opposite to each other in the pin layout. This page was uln2008 datasheet edited on 10 Februaryat The drivers can be paralleled for even higher current output.

Input for 5 th channel. Each channel or darlington pair in Uln2008 datasheet is rated at mA and can withstand peak current of mA. Generally it can also be used for interfacing with a stepper uln2008 datasheetwhere the motor requires high ratings which cannot be provided by other interfacing devices. Typical usage of the ULNA is datasueet driver uln2008 datasheet for relayslamp and LED displaysstepper motors, logic buffers and daatsheet drivers.
