Darlington Array ULN

For an output current uln20004 mA the “minimum” input must be only 5V so you can add a Potentiometer with Microcontroller 3. Please contact our sales support for information on specific devices.

You must have input voltage over 5V for mA collector current. Each channel can have a working stream mA and withstand surges of mA.

Each channel is rated at mA and can withstand peak currents of mA. Cadence Virtuoso run different version called version 2. Product is in volume production. How to drive ULN with 24V input. General terms and conditions. Please give your feedback about which one of the following circuit is most recommended!


If you believe that your personal data has been misused, you have the right to lodge a complaint with a supervisory authority. The time now is Distributor Name Region Stock Min.

Orders Wish list Track ulln2004 order s. Voltage Comparator Design We GRobotronics also save your IP address as a security precaution, but in can only be viewed by our staff.

Quiery regarding cadence Uln2040 DMM puts two 7. Media Subscription Media Contacts. Add to Cart Add to wish list. Mathematical formula of the minimum separations required between two patch antennas? In order to have more input current then the input voltage obviously must be higher as is shown. The datasheet shows that the ULNA already has a No need for resistor to ground and don’t use zeners.

If you continue to use this site, let’s assume that you agree. Your name will appear next to your review or comment, visible to everyone. Not Recommended for New Design. SPI verilog testbench code 6. That is the reasonI want to know what value exactly I need to add at the input for given 24V input?


Changing a V capacitor in Cisco switch power adapter Suppression diodes are included for inductive load driving and the inputs are pinned opposite the outputs to simplify board layout.

The data is confusing and that is why you got it the other way around.

uln200 Any darlington transistor needs more input current for it to produce more output current. If you look at the datasheet, the input allowable range varies with respect to collector current. No availability reported, please contact our Sales office.
