ULN2803A - Find the PDF Datasheet, Specifications, OEM and Distributor Information. ... Search Results: "ULN2803A" 545 parts found ... Motorola Solutions, Inc. Jan 02, 2010 · I pulled up the datasheet for the ULN2803 because I wanted to understand how a +5V pulse on its input could switch on the Optoisolated TRIAC. In the following image I added in RED example pins for how I understand it to be connected. I don't know if they are right or not. My actual question: I'm not sure how the circuit on the right actually ... ULN2803A from Motorola Solutions, Inc.. Find the PDF Datasheet, Specifications and Distributor Information.

At the nearly 5 volt output from the Stamp I/O pin, you can see that the current is expected to be in the 1.3 mA to 1.9 mA range. I just measured all the input currents on one ULN2803A, and they averaged 1.5 mA -- right on target. This device has another characteristic that should be kept ...
