Because of the Thanksgiving holiday in the U.S., TI E2E™ design support forum responses may be delayed from November 25 through December 2. Thank you for your patience.
Hi M,
Yes, this current spike is expected. Each inductive load draws a little less than 80mA, so when all 4 channels are turned off at once, the integrated flyback diode on the COM pin dissipates the current back to the COM source, so your COM current…
Part Number: ULN2803C Tool/software: Can the GND pin (9) be connected to a negative voltage other than circuit ground? I would like to use this device to drive 24V relays whose coils are connected to +/-12VDC. In this case the GND pin would be connected…
Part Number: ULN2803C Tool/software: Hello,
The following diode specifications can be found in the ULN2803C data sheet: https://www.ti.com/lit/gpn/uln2803c
Output clamp current = 500mA (max)
Clamp forward voltage = 1.3V (typ)
Clamp reverse current =…
Part Number: ULN2803C I've reviewed the data sheet and schematics for the subject part. As I understand it - this part has no suppression diode connected to Pin 20. Is that correct?
If you feel my claim is incorrect, could you please draw the path…
Part Number: ULN2803C Tool/software: Hi team,
The tPLH and tPHL seems incorrect in datasheet. Please help to check the value and the range of each. Thanks.

Part Number: ULN2803C Hello, I am a bit confused. I have been using the ULN2803 types in my designs and products for years. Unfortunately I have not received any information that the ULN2803ADW is being discontinued. Now the question for me is whether there…
Part Number: ULN2803C Hi team,
we are see that the others competitor ULN2803 device will follow 18pin package (Left) , but our ULN2803C(right) will have two more NC pins, customer can not directly use for P2P solution. can you help to update these device…
Part Number: ULN2803C Hi,
We currently use the ULN2803ADWR to drive a 4-digit, 7-segment display board.
Due to obsolescence, we replaced this part with the ULN2803CDWR part, however, we found that it is drawing slightly more current, but the brightness…
